Lung cancer is the number one cause of cancer deaths, both among women and among men. This cancer causes more victims annually than colon cancer, prostate cancer, lymphoma, and breast cancer together.
However, most deaths from lung cancer can be prevented, as smoking is responsible for nearly 90 per cent of all lung cancer cases. The risk of lung cancer is steadily increasing depending on the years and number of cigarettes smoked.
Quitting smoking, even after smoking for many, many years, can significantly reduce the risk of lung cancer. The risk of lung cancer can also be reduced by avoiding exposure to other factors that cause lung cancer, such as exposure to asbestos, radon gas and secondhand smoking.
