Metastatic cancer to the lung is cancer that starts somewhere else in the body and spreads to the lungs.

Metastatic tumors in the lungs are cancers that developed at other places in the body (or other parts of the lungs) and spread through the bloodstream or lymphatic system to the lungs. It is different than lung cancer that starts in the lungs.
Common tumors that spread to the lungs include:
However, almost any cancer has the ability to spread to the lungs.
Note: In most cases, there are no lung-related symptoms when the tumors are found.
Chemotherapy is usually used to treat metastatic cancer to the lung. Surgery isn't always done, because usually the cancer is in other parts of the body not seen by imaging tests. Surgery to remove the tumors seen on an x-ray is not likely to be helpful. However, surgery may be an option when:
However, the main tumor must be curable, and the patient must be strong enough to go through the surgery and recovery.
Other, less common treatments include:
There are other experimental treatments. One of these treatments uses local heat probes to destroy the area. Another places chemotherapy medicines directly into the artery that supplies blood to the part of the lung containing the tumor.
You can ease the stress of illness by joining a support group where members share common experiences and problems. For this condition, see cancer support group.
A cure is unlikely in most cases. It is rare for someone to live more than 5 years with metastatic cancer to the lungs. However, the outlook depends on the specific type of primary cancer.
You and your family may want to start thinking about end-of-life planning, such as:
Call your health care provider if you have a history of cancer and you develop:
