Lung cancer is the growth of abnormal cells that is uncontrolled. It can occur in one or both lungs. These developing cells will not function like normal cells or grow into healthy lung tissue. They will form tumors and impede oxygen reaching the lungs.
Lung cancer comes in two forms. One is a non small cell lung cancer and the second is small cell lung cancer. The difference between the two are how they look under microscope to pathologist. Most lung cancers consist of the non small cell. The oncologist will help determine what treatment is needed and will work best for your specific type of cancer.
Nearly 90% of lung cancer is caused by smoking tobacco. Quitting smoking will help reduce the risk of lung cancer. Exposure to secondhand smoke is also a large risk of lung cancer.
