Answer

Diagnosis

The etiology of carcinoid tumors is not known, but genetic abnormalities are suspected. Reported chromosomal abnormalities include changes in chromosomes, [18, 19] such as loss of heterogeneity, and numerical imbalances. The diagnosis is sometimes made because of unrelated findings, such as anemia, endocrine disease, or autoimmune disorders.
