Learn How To Prevent Lung Cancer

Lung cancer is a malignant disease commonly associated with people who smoke heavily. It is estimated that more men suffer from this form of cancer. Last but the number of women with lung cancer is still catching up with the number of men affected by disease.Diet is an important measure to prevent lung cancer. The risk of lung cancer for smokers and nonsmokers are both down when they eat at least five servings of fruits and vegetables per day. Among the major fruits and vegetables should be included in your diet are apples, tomatoes, melons, mangoes, leafy vegetables and onions. Apple and onion are rich in flavonoids against cancer. According to a study conducted in Finland, people who eat more than 58 percent of the apples less likely to develop lung cancer than those who do not eat apples all.Try add the tomato sauce in your kitchen.

Research shows that tomatoes, especially cooked dry protective properties against lung cancer.Taking large amounts of beta-carotene may also reduce the risk of lung cancer in smokers. Carotenoids are compounds found in some products, such as peaches, mango, melons, pumpkins, sweet potatoes, pumpkins and green leafy vegetables. supplements of beta-carotene, however, should be avoided. Study by the Finnish group has shown that 18 per cent increase in lung cancer was seen as heavy smokers who took beta-carotene supplements. In addition, the National Cancer Institute researchers also stopped to study the effects of vitamin A and beta-carotene after smokers who took the supplement showed lung cancer by 28 percent more than having an important measure for placebos.Another the prevention of lung cancer is a routine medical examination. This would also be accompanied by preventive medicine and supplements.

However, you should consult your doctor prophylactic benefit of aspirin, because this form of treatment becomes known as half effects.Selenium which is frequently found in multivitamins and minerals also show properties that prevent cancer, especially when you take a long time . Some studies show that those who take supplements of selenium, an exhibition of approximately 46 percent lower lung cancer rate.Vitamin C is also good for the prevention of lung cancer. Some studies suggest that people who regularly take 140 mg or more of vitamin C have a lower risk of lung cancer in the developing world than those who only get a 90 mg or less of vitamin C dosage.Lifestyle change is also important for the prevention of lung cancer. People who smoke should stop to consider the habit. When someone stops smoking, your risk of lung cancer is reduced by almost half in 1910 years.Finally, the second most common cause of lung cancer is exposure to radon, a colorless gas, the earth.

An X-ray is necessary especially for people who smoke and are under 50 years or more. A yearly chest X-rays will be particularly beneficial for people who are at high risk of developing lung cancer. A chest radiograph is a preventive measure done to screen for lung cancer. A routine chest X-rays allow doctors to diagnose lung cancer early so that appropriate treatment procedures implemented.Aspirin has been shown to prevent lung cancer, especially when the dose of 81 to 325 mg taken every days.

Test your home from any of the presence of radon. You can buy a do-it-yourself kit to control radon, which is available at home stores or you can hire a professional to do it for you.

3 Non-Small Cell Lung Cancer Treatments explained

There are two main types of cancer cells in metastatic non-small cell (NSCLC) lung cancer and small cell (SCLC). Of the two, cancer is more common, representing 80% of cases. Begins when cells in the lung begin to grow and multiply rapidly and uncontrollably. Over time this can cause a malignant (cancerous) in the lungs that kills the surrounding cells, and then grows. Although this condition is life threatening is a series of treatments that can be used depending on how advanced the cancer has become. In this article I will discuss these three treatments NSCLC.

1) kirurgi: Leikkaus that yleensä syöpiä käytetään, jotka eivät ole leviää keuhkoihin. It Kåks olemassa leikkaus päätyyppiä, Etta ei-NIIT keuhkosyöpä pienisoluinen käytetään.

Kuitenkin, Jos syöpä that levinnyt ehkä koko Sitten Yli koru that keuhkojen poistettava kutsutaan prosessia pneumonectomy.

2) Chemotherapy involves using drugs that kill cancer cells to treat NSCLC. It is often used when cancer has become more advanced, surgery is no longer a viable option. However, it also can be used before surgery (to reduce cancer cells and make the procedure easier to perform) or after surgery (to kill cancer cells and reduce the risk of recurrence). Unfortunately, chemotherapy is not perfect and has a number of unpleasant side effects associated, including general malaise, poor appetite and loss of hair. However, in most cases, these symptoms disappear when the course of the chemotherapy is over.

3) STRÅLEBEHANDLING: Onkologie omfattar anvendelse Høje tested af af ødelægge kræftceller Straling up.

Det kan dog for witches OGSA og Efter gore operation in udføre det lettere, og chancerne Kommer tilbage Reducere for NSCLC.

Cancer is a terrible disease and learning that have developed in non-small cell lung can be very unpleasant. However, remember that you can treat especially when found at an early stage. I hope this article gave an overview of possible treatments NSCLC, but to get the whole picture, you should see your doctor. They will be able to provide professional advice and we offer the most appropriate for treatment.Whilst has been done to make this article accurate and informative, it is intended for general information only. Lung cancer is a very serious, life-threatening condition and you should discuss any concerns, treatments or lifestyle changes fully with your doctor.

How To Prevent Lung Cancer For Smokers

Lung cancer is a terrible disease that kills thousands of people every year. The vast majority of these cases were from smokers, but also many people who quit smoking for many years before. How to prevent lung cancer should be of great concern to all those who have smoked for a long period of their life you are in the category of high risk of lung cancer, throat and mouth.

Preventing Lung Cancer Basics

The first thing you do if you want to avoid becoming a statistic cancer is to quit smoking. The obvious, of course, but it's amazing how a strong dependency on cigarettes can make people think they can clean the lungs and cancer, and continues to smoke. It is an inescapable fact that smoking is stopped the risk of lung cancer early reducing.From At this stage you are not sure yet, but as tar in cigarettes to lung cancer in the traps. Your body takes a long time to remove the tar and toxins to clean without the active work on your part. So need to start cleaning chemicals that cause lung cancer.

Foods that prevent cancer of the lungs

Some foods may help to achieve better lung health and prevent yourself from becoming a statistic second tumor. These are foods that contain antioxidants, which are attached to prevent cancer of any kind. Some of these foods are green tea, oregano and broccoli, but much more exist.Other foods can help to more indirect forms. Some foods simply to help the immune system, so that aides the body's natural detoxification and lungs.Another to help is to eat foods that liquefy mucus in the lungs, such as chili and other hot dishes. This allows you to easily remove the mucus that contains tar and toxins that cause cancer.

Detoxification to prevent lung cancer lung

Along with foods that will help you to detoxify the lungs, there are many other ways that you can clean the carcinogens. A combination of vitamins, and mental and physical exercises can help clean the lungs and prevent lung cancer.

Exposure To Asbestos And Lung Cancer

asbestos in the United Kingdom accounted for 2-3% of male deaths from lung cancer. It is a complementary effect between tobacco smoking and asbestos in the formation of lung cancer. Asbestos can also cause pleural mesothelioma, or (which is different from lung cancer). The people who work with asbestos are at higher risk of lung cancer. People are exposed to industrial materials or construction materials such as asbestos, nickel, chromium compounds, arsenic, polycyclic hydrocarbons and chloromethyl ether is also a higher risk of developing lung cancer. It 'also important to try to avoid another second-hand smoke, radon, and pollution, which may increase the risk of a person cancer.People lung cancer who have been exposed to asbestos lung cancer were diagnosed in only twenty or thirty years down the road. If you suspect that you may be exposed to the risks described above, watch out for symptoms related to lung cancer.

• dyspnea (breathing difficulty)

• hemoptysis (coughing up blood)

• chronic cough or change in regular coughing pattern

• wheezing

• chest pain or abdominal pain

• cachexia (weight loss)

• fatigue and loss of appetite

• sphonia (hoarseness)

• clubs fingernails (uncommon)

• dysphagia (difficulty swallowing).

• Recurrent chest infections

• Asthma

• The fluid around the lungs

• swelling of the neck or face

• drowsiness

Some lung cancers do not cause noticeable symptoms until they are quite advanced and have spread to other parts of the body. When people have symptoms of lung cancer is usually in the fourth stage, which has already begun to disseminate the main organ.Additional symptoms may also occur with lung cancer include:

• Swallowing difficulties

• Nail Problems

• Joint pain

• facial paralysis

• drooping eyelid

• Bone pain or tenderness.

Effects of Lung Cancer

Lung cancer is destructive by itself. Lung cancer hormones also affect the functioning of the kidneys making it very difficult to excrete urine.In additional to mechanical damage and hormonal damage the malignant tumors of the lungs produce a wide range of general side effects and not all of them are fully understood. These include nausea, loss of appetite, anemia, fever, skin rashes, weakness, abnormalities of taste sensation and severe loss of weight. In addition lung cancer tumors have much greater demand for amino acids which are the building blocks of proteins as compared to the normal cells. They may derive these amino acids from the patient's muscles leading to body wasting.The cause of death due to lung cancer is usually a combination of several factors like cachexia, infection, internal bleeding, compression and destruction of lungs.Do you still want to smoke or be around anyone who does?In addition lung cancer has general effects. Lung cancer cells produce hormones that affect the calcification of bones (i.e.) calcium deposits are made in joints of the bones which will make the movement very rough and painful. They also affect the output of the adrenal glands thereby leading to uncontrolled blood pressure. Lung cancer hormones also affect the functioning of the kidneys making it very difficult to excrete urine.In additional to mechanical damage and hormonal damage the malignant tumors of the lungs produce a wide range of general side effects and not all of them are fully understood.

Four Stages of Lung Cancer

In order to know the kind of treatment that a cancer patient must undergo, the medical team must first identify the stage of lung cancer being experienced by the patient. Once a person undergoes the clinical staging of cancer, diagnosis is being done.Staging is the process of describing the extent of the disease. Cancer staging is based on the pathology report coming from a series of diagnostic examinations.One of the most common forms of diagnostic exam is bronchoscopy which uses a small device allowing the surgeon to view both lungs in order to identify how far the cancer has metastasized.Below are the four stages of lung cancer which are evident in people who are affected with the disease.
Stage 1 Lung Cancer
Here, the cancer is still localized which means that the disease concentrates mainly on the area where it started to grow. There is absence of cancer on the adjacent lymph nodes and it has not reached any kind of metastasis to other parts of the body.The first stage of lung cancer can be divided into two stages namely Stage IA and Stage IB.Stage IA manifests that the tumor is sized to about three centimeters, even less and is fairly small.Stage IB displays that the tumor will be larger than three centimeters and to be specific, it is growing within the bronchus. In this stage, the cancer may cause the lungs to partially collapse.
Stage 2
Here, the stage is divided into two: Stage IIA and Stage IIB.In Stage IIA, the cancer is small although it is starting to spread to the adjacent lymph nodes. While in Stage IIB, the disease is at least three centimeters wherein there could either be an apparent metastasis to the lymph nodes or, instead of affecting the lymph nodes, it has spread to the surrounding tissue.
Stage 3
In Stage 3 lung cancer, it could either be IIIA or IIIB.Stage IIIA indicates that the cancer has spread further to the lymph nodes from the lung being affected or the cancer is apparent in the nodes that is near the affected lung and has spread to the tissue surrounding it.In Stage IIIB, the cancer will occur if there is a spread to the adjacent lymph nodes that is located on the other side of the chest or even above the clavicle or collarbone. Stage IIIB can also happen if the disease has spread to a different structure within the chest like the heart.
Stage 4
This is considered as the most advanced stage of the disease. Here, the lung cancer has affected another lung lobe or has already reached another part of the body, like the brain, aside from the inside of the chest like the stomach and even the liver.In order to treat lung cancer, a variety of methods can be used which is just similar to the different kinds of cancers which may occur in the body, although, in order to find the appropriate treatment, one should be diagnosed first with the correct staging based on the four stages of lung cancer. Some of the treatments include surgical removal of the cancer-affected lung, chemotherapy and radiation therapy. The percentage of success in treating the cancer will depend on the extent that the cancer has affected a person's lung.

The Stages And Treatments For lung cancer

Lung cancer forms in the tissues of your lungs generally in the cells which line your air passages.lung cancer is a very aggressive type of cancer and if not caught early enough can have a very poor outcome.Generally, lung cancers originate in the lining of the bronchi. Plus it can also form in the glands below the lining of the bronchi, usually in the periphery of the lungs.There are four recognizable stages of lung cancer. Stage one is the mildest and stage four is the most severe form. Remember though, that all stages of lung cancer are very serious.
Let us now examine the four stages:

1. Stage One: In this stage, the cancer is confined to the lung tissue will only. Your chance of recovering from this type of cancer is the best.
2. Stage Two: Here the cancer is confined to the lung tissue and lymph nodes only.
3. Stage Three: At this stage, the cancer is in the lung tissue and lymph nodes inside and outside the lungs.
4. Stage Four: When you reach this stage, the cancer has spread to the liver, bone, adrenal glands, brain, and other areas.

The state of development and the type of the cancer are very important when trying to heal the patient. There are two types: Non-Small Cell Lung Cancer, and Small Cell Lung Cancer. What follows are the likely treatments and approximate cure rates for each stage of lung cancer:

• Stage One: The main treatment here involves surgery.Cure rate is around 67%.
• Stage Two: The main treatment for this type of cancer also involves surgery.The cure rate for this type of cancer is generally in the 40 to 50% range.
• Stage Three: The main treatment here includes chemotherapy and radiation.The cure rates is generally less than 60%.
• Stage Four: The main treatment involved here also includes chemotherapy and radiation. The cure rate at this stage is less than 80%.

Research is continually ongoing to study the causes of lung and other cancers, and to find new ways to prevent or even cure them.Unfortunately however, if you are diagnosed with lung cancer there is not a very good outlook attached to the outcome.

What Are The Early Symptoms of Lung Cancer?

Lung cancer takes time to produce chronic and severe symptoms. Therefore, it is important that one knows the different early symptoms of lung cancer in order to recognize the disease early and prompt treatment can be given. According to statistical reports, lung cancer ranks first in the majority death rate in either male or female. This is one main reason why medical practitioners and people involved in maintaining the stability of people's health are eager to lessen the occurrence of the disease by manipulating the environment. Usually, cancer becomes evident from the age of 40 going to 70. The moment cancer cells becomes malignant, it is termed as lung cancer in the primary stage. If a person gets lung cancer and he or she is not a smoker nor is exposed long-term to chemicals and lung irritants, it is deemed that the cancer may have come some place else from the body. The spread on the lungs commonly comes from the bone, stomach, lymph nodes, breast, kidneys, skin, colon, cervix and even testis.Some of the common signs and symptoms of cancer are: nagging cough which doesn't go away in weeks or month's time, chest pain, recurrent bronchitis or pneumonia problems, hemoptysis or coughing blood-stained sputum, easily fatigued, weight loss which is caused by anorexia or loss of appetite, and lung manifestations like Dyspnea, hoarseness and wheezing.Once the early signs and symptoms occur, oftentimes the cancer is diagnosed as severe or has metastasized to a nearby body part like the lymph nodes. Some evident symptoms seen in patients having lung cancer are:

• Dysphagia or difficulty in swallowing - which is considered as one of the serious symptoms of lung cancer for it may not allow the cancer patient to ingest food and even liquid.
• Abnormalities affecting the fingers or the fingernails like overgrowth of tissues in fingertips that result to clubbing
• Gynecomastia or the development of breasts in men
• Atrophy or shrinkage of the muscles
• Above all, the three main symptoms related to lung cancer that must not be set aside are the following:
• Chest pain that is a result from persistent coughing or even at the extent of abnormal breathing.
• Hemoptysis or coughing out of blood-streaked sputum which may indicate that trauma is now being experienced by the respiratory system.
• Shortness of breath can happen if there is a blockage in the bronchioles or tubes which serves as a passageway for oxygen.

The Truth Behind the Metastatic Lung Cancer

Unlike other forms of lung cancer, metastatic lung cancer is the result of a cancer from another part of the body spreading to the lungs. When a malignancy develops in the body (most often in the breasts, colon, prostate, or bladder, though almost all cancers have the ability to spread) it can sometimes spread through the blood stream. Unfortunately, treating metastatic lung cancer presents significant challenges. Since the cancer has spread from another part of the body, treatment not only involves addressing the cancer in the lungs, but also the original cancer and any other areas of the body that may have also become affected. In some cases, if the primary tumor is successfully removed and if the spread of the tumor cells to the pulmonary regions is relatively localized, then the management of the cancer by surgical techniques may do the job. However, if the metastatic lung cancer is extensive, because so many areas of the body may be under the influence of the cancer, certain treatments (such as surgery, and in many cases, radiation therapy as well) may prove ineffective. Which leaves most patients with chemotherapy as the primary treatment of choice.Chemotherapy often uses a combination of drugs (often referred to as "anti-cancer" drugs) to kill cancer cells, though a single drug may be used as well. While the aim of these drugs is to stop cancerous cells from multiplying, they also can damage healthy cells. Chemotherapy can provide a cure (when the cancer disappears and does not return) or help to control the cancer (to keep it from spreading and perhaps kill cancerous cells that have already spread to other areas of the body, such as is the case in metastasized lung cancer) or relieve the symptoms of the cancer (to provide the patient with a better quality of life, even in the face of a poor prognosis). Metastatic lung cancer is certainly more challenging to overcome than other forms of lung cancer because the fight against the cancerous cells is not confined to the lungs. And while a cure is unlikely in most cases, in rare instances (usually when the primary tumor has been removed and the spread of the cancer has been limited), the lung metastases can be removed surgically, with a prognosis of long-term survival.It should not be used during a medical emergency or for the diagnosis or treatment of lung cancer or metastatic lung cancer. Such situations should always involve the expertise of a physician or health care provider.

How To Prevent Lung Cancer

Lung cancer is a malignant disease commonly associated with people who smoke heavily. It is estimated that a higher number of men are suffering from this form of cancer. Lately however, the number of women affected with lung cancer is steadily catching up with the number of men affected with the disease.Diet is an important measure in preventing lung cancer. The risk of developing lung cancer for smokers and non-smokers alike are lowered when they eat at least five servings of fruits and vegetables daily. Among the most important fruits and vegetables that should be included in your diet are apples, tomatoes, melons, mangoes, dark leafy greens and onions. Apple and onion are rich in cancer-fighting flavonoids. According to a study conducted in Finland, people who consume more apples are 58 percent less likely to develop lung cancer than those who do not eat apples at all.Try to add some tomato sauce in your cooking. Research shows that tomatoes, especially cooked ones, seem to exhibit protective properties against lung cancer.Taking in high amounts of beta-carotenes can also lower the risk of lung cancer in smokers. Carotenoid compounds are found in certain produce like peaches, mangoes, melon, squash, sweet potatoes, pumpkins and green leafy vegetables. Beta-carotene supplement however should be avoided. A study conducted by a Finnish group indicated that an 18 percent rise in lung cancer cases was seen in heavy smokers who were taking beta-carotene supplements. Moreover, the National Cancer Institute researchers also stopped their study on the effects of vitamin A and beta-carotene after smokers who were taking the supplements showed 28 percent more lung cancer than those taking placebos.Another important measure in the prevention of lung cancer is a routine medical check-up. This should also be accompanied with prophylactic medicines and supplements. An x-ray is necessary especially for those people who smoke and are at the age of 50 and above. A yearly chest x-ray will be especially beneficial for those people who are at high risk of developing lung cancer. A chest x-ray is a preventive measure done to screen for lung cancer. A routine chest x-ray will enable doctors to diagnose lung cancer early so that proper treatment procedures will be implemented.Aspirin has been shown to ward off lung cancer especially when a dosage of 81 to 325 mg is taken daily. However, you should consult your doctor about the prophylactic advantage of taking aspirin since this form of therapy comes with known side effects.Selenium that is often found in multivitamin and mineral supplements also shows properties that ward off cancer especially when taken over a long period of time. Some studies show that those who are taking selenium supplements exhibit about 46 percent lower lung cancer rate.Vitamin C is also good in the prevention of lung cancer. Some studies suggest that people who regularly take 140 mg or more of vitamin C have lower risk of developing lung cancer than those who only get 90 mg or less of vitamin C dosage.Lifestyle change is also vital in the prevention of lung cancer. People who smoke should consider quitting the habit. When a person stops smoking, his lung cancer risk is lowered by almost half in 10 years.Finally, the second most common cause of lung cancer is exposure to radon, a colorless gas found in the ground. Test your home for any presence of radon. You can either buy a do-it yourself kit to check for radon which is available in your home supply stores or you can hire a professional to do it for you.

4 Major Risk Factors For Small Cell in the Lung Cancer

Lung cancer can be broken down into two types; small cell lung cancer (SCLC) and non-small cell lung cancer. SCLC accounts for approximately 20% of all lung cancers. It is often referred to as oat cell carcinoma because the small cells of the lung have a similar appearance to oats. SCLC develops when there is a rapid and uncontrollable growth in the small cells of the lung that eventually leads to a malignant (cancerous) tumour forming.

1) SMOKING:- Tobacco smoke is the leading risk factor for all types of lung cancer. The reason that tobacco smoke is such a strong risk factor for SCLC is that it is full of carcinogens (cancer causing substances). According to Cancer Research UK tobacco smoke can contain up to 70 different carcinogens. When you inhale tobacco smoke (either directly through a cigarette or indirectly through second hand smoke) these carcinogens go straight to your lungs greatly improving the risk of lung cancer and SCLC developing.
2) URANIUM:- Exposure to uranium is thought to increase your risk of developing all types of lung cancer. However, it is most strongly linked with the development of SCLC. A combination of uranium exposure and exposure to tobacco smoke increases your chances of developing SCLC even further.The reason uranium increases your risk of contracting SCLC is that uranium ores are radioactive. Research has shown that prolonged exposure to radioactive materials can cause cancer.
3) ASBESTOS:- Asbestos is most strongly linked with a rare kind of cancer called mesothelioma. However, it has also been linked with increasing the risk for other types of lung cancer including SCLC. Asbestos exposure combined with tobacco smoke greatly increases your small cell lung cancer risk.The reason asbestos increases your chances of developing SCLC is that when it becomes disturbed very fine fibres are released. These fibres irritate the body's cells and can lead to the development of cancer. If they become lodged in the small cells of the lung they can stimulate the development of SCLC.
4) POOR DIET:- According to Cancer Research UK not getting enough fruit and vegetables in your diet can increase your risk of developing SCLC. If you are deficient in any of these then the small cells of your lung may be more susceptible to cancer.SCLC is not a pleasant condition. However, unlike many other types of cancer where the risk factors are unclear, SCLC has a number of very definite risk factors. In particular smoking has been scientifically proven to significantly increase your small cell lung cancer risk.

Lung Cancer and her Stages of Malignancy

Lung cancer, like any other malignancies, is the outcome of abnormalities the cell, which is the essential unit of life of the human body. Usually, the body keeps up a system of checking and balancing the cell growth in order that the cells can divide in producing fresh cells only if there is necessity of new cells. Tumor has two categories, the benign and the malignant tumors. Malignant tumors grow assertively and attack other parts or tissues of the body, permitting the entry of cancer cells into the lymphatic system or to the bloodstream and some other locations in the human body.Metastasis is the process of spreading the tumor cells and the spots of the growth of tumors at these distant sites are known as metastases. While cancer of the lung may spread to some organs in the body, particular organs, like liver, brain bones and adrenal glands are the commonly the sites for the metastasis of lung cancer.Tumor metastases consist of similar types of cells being the original tumor. The lung is extremely the common location for metastasis coming from tumors in some parts in the body. For example, when cancer of the prostate scatters through the bloodstream into the lungs, it could not be lung cancer but it is prostate cancer which metastasized in the lungs.The exchange of gases between the blood and the air we are breathing if the primary role of lungs. Carcinoma of the lungs may arise in some parts of the lungs, but ninety to ninety five percent of lung cancers are considered to come from epithelial cells; the cells coating the smaller and larger airways (bronchi and bronchioles); because of this, cancer of the lungs are occasionally called broncogenic cancers or carcinomas.(carcinoma is another term for cancer). Mesothelioma is a type of cancer that arises from pleura or seldom from supporting tissue in the lungs, blood vessels for example.Physicians can use various examinations to stage accurately lung cancer, which includes blood chemistry tests, CT scan, MRI, X-rays, PET scans and bone scans. Staging of lung cancer is essential to determine how the tumor can be treated, because lung-cancer therapies are done toward particular stages. Staging of cancers are also serious in the estimate of the prognosis of patient, having higher-stage carcinomas usually having worse diagnosis than lower-stage malignancy.

Cancers are assigned the following stages:

1. Stage I - the cancer is limited to the lung only .
2. Stage II and III, the carcinoma is limited in the chest (with bigger and more persistent tumors classified to be stage III).
3. Stage IV - the cancer has scattered from the chest and other parts of the body.

Necessary Steps for Lung Cancer Prevention

Research continues to show that the most common cause for lung cancer is the use of tobacco. Lung cancer typically develops over a long period of time. The first pre-cancerous changes that form in the lungs mutate and produce chemicals that result in the formation of new blood vessels. These blood vessels nurture the cancer cells. The cancer cells grow together and form a tumor. These cancer cells have the ability to easily spread to other parts of our body even before the cancer is detected. This process is known as metastasis and is one of the main reasons why lung cancer is so fast moving and life-threatening.Lung cancers are classified as small-cell lung cancers and non-small-cell lung cancers. Non-small-cell lung cancer is further divided into three types, known as squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. In the United States alone, about 213,380 people are estimated to be suffering from lung cancer, with nearly 160,390 deaths occurring in the year 2007. Current data shows that lung cancer accounts for 29% of all cancer deaths. About one-third of cancer and 80% of lung cancer are caused by the usage of tobacco, either directly or indirectly.Lung cancer prevention methods are very important because of the difficulty to detect lung cancer until it is in an advanced stage, when treatments are really not effective. A few simple steps have the potential to prevent the incidence of lung cancer. Smoking and the use of tobacco products should be completely avoided or stopped. Data reveals that long-term cessation of smoking reduces the incidence of lung cancer by over 50%. Exposure to radon gas and other carcinogens like petroleum products should be avoided.A healthy diet consisting of more vegetables and fruits is highly recommended. Nowadays, many governments have initiated active anti-smoking programs and advertising campaigns because of the strain on the health care system that tobacco products add to it. Many of them also impose high taxes on tobacco products to discourage tobacco users. Several nations have enacted strict laws towards smoking in public places including workplaces and for restricting tobacco access to minors. Studies reveal that smoking bans in workplaces effectively reduce the exposure to environmental tobacco smoke (ETS) by 72%.Mass media anti-tobacco campaigns reduce the initiation of new persons to tobacco, decrease tobacco consumption, and increase cessation of tobacco. A sustained multi-pronged approach alone could create mass awareness about lung cancer prevention. When more and more people realize the harm caused by tobacco, consumption would decline and the effects on lung cancer cases would be immense as well as other health concerns like heart disease, stroke and hypertension.
