ANNOUNCER: In most patients with stage I or stage II disease, the cancer is resectable, which means it can be removed surgically. If a patient is well enough, treatment usually begins in the operating room.
EDWARD S. KIM, MD: The early-stage lung cancer is treated with surgery and, generally, this is at least with a lobectomy.
There are three separate lobes or areas of your right lung and two on your left lung. If a tumor falls within one of those discrete areas, then that lobe is removed which encompasses the tumor.
ANNOUNCER: Radiation is sometimes used, too. But mostly for people who are elderly and frail, or who otherwise cannot tolerate surgery.
A lung cancer patient's chances for survival depend on how the disease may have spread.
CHRISTOPHER G. AZZOLI, MD: If you have stage I disease, and you have successful surgery and removal of the cancer, your chance of being alive in five years is 60 to 80 percent. If you have stage II, it's 40 to 60 percent. And if you have stage III, it's 20 to 40 percent.
ANNOUNCER: There's always the possibility lung cancer returns after surgery. That's usually a very dangerous situation.
CHRISTOPHER G. AZZOLI, MD: If lung cancer were to come back after a successful surgery, chances are it would come back some place outside of the chest, which means that, before the surgeon had a chance to take the cancer out, cells had broken off, gotten into the bloodstream and moved around the body.
