'''Carcinoid tumors''' are rare, slow-growing [[cancer]]s that usually start in the lining of the [[digestive tract]] or in the [[lung]]s.

In later stages the [[tumor]]s sometimes produce [[hormone]]s that can cause [[carcinoid syndrome]]. The syndrome causes flushing of the face and upper chest, diarrhea, and trouble breathing.{{fact}}
