'''Carcinoid tumors''' are rare, slow-growing [[cancer]]s that usually start in the lining of the [[digestive tract ]] or in the lungs[[lung]]s. Because they grow slowly and don't produce symptoms in the early stages, the average age of people diagnosed with digestive or lung carcinoids is about 60.{{fact}}
In later stages the tumors [[tumor]]s sometimes produce hormones [[hormone]]s that can cause [[carcinoid syndrome]]. The syndrome causes flushing of the face and upper chest, diarrhea, and trouble breathing.{{fact}}
Surgery is the main treatment for carcinoid tumors. If they haven't spread to other parts of the body, surgery can cure the cancer.{{fact}}<ref>http://www.nlm.nih.gov/medlineplus/carcinoidtumors.html</ref>
