In men and women, lung cancer is the second most common type of cancer, and most of the deaths are caused by lung cancer among men and women. The death rate caused by lung cancer is far more, greater than breast cancer and prostate cancer. There are many symptoms of lung cancer, but these symptoms may not appear at early stages until the disease is advanced. Symptoms of lung cancer appear in the chest and elsewhere in the body.
