The lungs are the two organs located beneath the rib cage that provide life-sustaining oxygen throughout the body. They are neither symmetrical nor functionally identical, with the left lung consisting of two lobes and the right three. Lung cancer begins when cells of a lung become abnormal and begin growing out of control. When the abnormal cancer cells grow, they can form into a tumor and even spread to other areas of the body (metastasize).
Review this section's important information about lung cancer diagnosis, staging, and treatment options, as well as lung cancer patient and survivor resources as you prepare for an appointment with your oncologist. After reviewing these sections, ask your cancer care team any additional questions that you may have about your individual situation.
