Lung cancer is a disease of uncontrolled cell growth in lung tissues. This growth may lead to metastasis, invasion of adjacent tissue and infiltration beyond the lungs.
Lung cancer is one of the most common cancers in the world that can affect everyone and difficult to treat. That’s why we should try to prevent this terrible disease. Fortunately, lung cancer is also one of the most preventable type of cancer. By avoiding certain risk factors for lung cancer you can significantly reduce the risk of developing lung cancer. Here are some effective ways to prevent lung cancer.
- Avoid tobacco smoke
The first and the most effective ways to prevent lung cancer is to avoid tobacco smoke. Don’t start to smoke if you do not already, and if you do, stop smoking now. Although quitting smoking can be very hard but it is not impossible. Millions of people have done it. Recent studies suggest that those who can quit smoking reduce their chances of developing lung cancer by 30-50 percent.
- Avoid secondhand smoke
Try to avoid areas where people smoke, such as bars and restaurants, and seek out smoke-free options. Non-smokers who inhaled second-hand smoke are exposed to the same cancer-causing agents as smokers, although in weaker amounts. Inhaling second-hand smoke is called involuntary or passive smoking. If you live with a smoker, urge him or her to quit. At the very least, ask him or her to smoke outside.
- Eat a healthy diet
Studies show that a diet rich in fruit and vegetables can lower the risk of getting lung cancer, while heavy alcohol drinking may increase the risk of lung cancer.
- Be physically active
Studies show that people who are physically active may have a lower risk of lung cancer than those who are not, even after taking cigarette smoking into account.
- Prevent or limit exposure to carcinogenic substances
Exposure to certain carcinogenic (cancer-causing) substances, such as asbestos, radon, arsenic, and coal products, in the workplace or at home can also increase the risk of developing lung cancer.
- Avoid taking beta carotene supplements
Studies show that heavy smokers who taking beta carotene supplements may further increasing their risk of lung cancer compared with smokers who don’t take beta carotene supplement. A study conducted by a group of Finland showed that 18% increase in lung cancer cases seen in heavy smokers who took beta-carotene supplements. However, for non-smokers taking beta carotene supplements does not affect the risk of lung cancer.
