How to prevent lung cancer?

Prevention of lung cancer includes quitting smoking and avoiding exposure to potentially cancer-causing substances in the work environment. The best way to prevent lung cancer is not to smoke or to quit smoking if one has already started. Educational efforts, aggressive public health campaigns, anti-tobacco legislation, over-the-counter nicotine replacement

therapies combined with specific antidepressants (eg, Zyban), and intense social pressures that "denormalize" smoking are helping smokers to quit. Secondhand smoke from other people's tobacco should also be avoided.

Eat well-balanced meals. Diets rich in fresh fruits and vegetables may be protective against lung cancer in both smokers and non-smokers. In any case, diets with plenty of fresh fruits and vegetables are rich not only in important vitamins but also in other beneficial nutrients called phytochemicals ( phyto simply means plant) that are necessary for all aspects of health. Important cancer-fighting phytochemicals include isothiocyanates found in the cruciferous vegetables (eg, broccoli, cauliflower, and Brussels sprouts), flavonoids (major sources are apples, grapefruit, onions, red wine, and tea), soy protein, and lycopene. Diets high in animal fats increase the risk for lung cancer. Others have suggested some protection from cod liver oil, which contains omega-3 fatty acids (found in fatty fish), omega-6 fatty acids (found in flax and soybean and canola oil), and monounsaturated oils (found in olive and canola oils). Despite these intriguing pieces of information, the ability of these substances to protect against lung cancer remains controversial, and discontinuation of smoking remains the best advice. Some B vitamins are being considered as cancer fighters. Folic acid and B12 convert the amino acid homocysteine to methionine, which in turn protects genes that help prevent malignancies in cells. Vitamin A and nutrients called carotenes (some of which convert to vitamin A) have been researched for possible protection against lung cancer. Selenium appears to inhibit cell proliferation and may have other anti-carcinogenic properties.

Test houses for the presence of radon gas, and removing asbestos from buildings are also useful preventive strategies. People concerned about radon in their home or area can purchase a test approved by the Environmental Protection Agency. Methods for removing radon include installing a soil suction system. It should be noted, however, that home prevention measures rarely reduce radon levels to zero. Simply sleeping by an open window reduces the risk.

How is lung cancer diagnosed? - Diagnosis of lung cancer may be made by physical examination, chest X rays, bronchoscopy, or percutaneous needle biopsy. Lung biopsy is the most definitive diagnostic tool for cancer.
What're the lung cancer stages? - Lung cancer is staged according to its location, size, cell type, and spread. Knowing the stage of lung cancer helps the doctor set the treatment plan.
What're the treatments for lung cancer? - The treatment of lung cancer depends on the type and stage of the disease and includes surgery, radiation therapy, and chemotherapy.
What's the treatment for small cell lung cancer? - At limited stage treatments for small cell lung cancer include various combinations of chemotherapy, radiation.
What's the treatment for non-small cell lung cancer? - Surgery is the primary treatment for all non¨Csmall cell lung cancers. Radiation therapy may be administered.
Treatment for non-small cell lung cancer by stage - Stage III non-small cell lung cancer are treated with radiation and sometimes with surgery, chemotherapy, or combinations of each.
What's the prognosis of lung cancer survival rate? - The prognosis of lung cancer depends on the type of lung cancer, its stage, and the overall health of the patient.
How to prevent lung cancer? - Prevention of lung cancer includes quitting smoking and avoiding exposure to potentially cancer-causing substances in the work environment.
Asbestos lung cancer - The most serious hazard of exposure to asbestos is cancer. Lung cancer causes the largest number of deaths related to asbestos exposure.
