Lung Cancer Causes and Prevention

Causes of Lung Cancer
  • Smoking tobacco products in any form is the major cause of lung cancer. So stop smoking at any time before the disease has started & reduce the high risks.
  • Heavy alcohol drinking may increase the risk of lung cancer.
  • Air Pollution: Lung cancer rates are higher in cities with higher levels of air pollution.
  • Prolonged exposure to some industrial dusts (for example asbestos) increases the risk of lung cancer, particularly in smokers.
  • A family history of lung cancer: If you have a first degree relative with lung cancer, your risk of lung cancer is doubled. Families of smokers will all be exposed to cigarette smoke and so have an increased risk of lung cancer whether they have inherited a faulty gene or not.
  • People with a previous head and neck cancer, oesophageal or cervical cancer have an increased risk of lung cancer. But the fact is that the risk of these cancers is higher in smokers.
  • HIV and AIDS lowers immunity. People with HIV or AIDS have a risk of lung cancer that is 3 times higher than people who do not have HIV or AIDS. People who take dugs to suppress their immunity after an organ transplant have double the usual risk of lung cancer.
Prevention of Lung Cancer
  • Smoking tobacco products in any form is the major cause of lung cancer. People who stop smoking and never start again lower their risk of developing lung cancer or of having lung cancer recur (come back). Many products, such as nicotine gum, nicotine sprays, nicotine inhalers, as well as antidepressant drugs, may be helpful to people trying to quit smoking.
  • Second–hand tobacco smoke also causes lung cancer. This is smoke that comes from a burning cigarette or other tobacco product, or smoke that is exhaled by smokers. People who inhale 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.
  • Diet and physical activity: A diet rich in fruit, and possibly vegetables, may help lower the risk of lung cancer, while heavy alcohol drinking may increase the risk of lung cancer. People who are physically active may have a lower risk of lung cancer than those who are not.
  • Cancer–causing agents that may be found indoors, especially in the workplace, include asbestos, radon, arsenic, chromium, nickel, tar, and soot. These substances can cause lung cancer in people who have never smoked. Observe industrial safety regulations strictly in working areas where there are harmful dusts such as asbestos.
  • Lung cancer rates are higher in cities with higher levels of air pollution. So pollution levels should be monitored & controlled frequently.
  • Smokers and other high–risk groups should have regular chest X–rays.
