Living with Carcinoid tumor

A rare, slow-growing cancer that usually starts in the digestive tract or the lungs.

Understanding Carcinoid tumor

Carcinoid tumors are rare, slow-growing cancers that usually start in the lining of the digestive tract or in the lungs.

They often cause no symptoms early on, so people are usually diagnosed around age 60. In later stages, the tumors can make hormones that cause carcinoid syndrome, with flushing of the face and upper chest, diarrhea, and trouble breathing. Surgery is the main treatment.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.
