Secondary lung cancer originates from a cancer which has started somewhere else in the body. Secondary lung cancer most commonly develops from primary cancer of the breast, large bowel (also known as colon and rectum), gullet (oesophagus), melanoma (belonging to the skin cancer group), bladder, testicle, kidney (renal) and stomach.

Symptoms tend to mirror those of primary lung cancer.
