Is lung cancer serious?

Lung cancer is a very serious malignancy. It causes over 160,000 deaths per year in the United States. Usually there are symptoms of cough, shortness of breath and coughing of blood that can be very serious when patients have tumors that are obstructing their airways.

Lung cancer is serious, and is the leading cause of cancer-related deaths. It can spread to other organs, and treatment for the disease can be difficult with harsh side effects. Lung cancer diagnosed late in the disease usually causes death within six months. However, the leading cause of lung cancer, smoking, is avoidable. Even people who have smoked throughout their life can enjoy a reduced risk of lung cancer by quitting now.
