Definition:
Carcinoma is a very common type of cancer. Carcinomas can occur in many different places. Examples include the colon, skin, and lungs.
What carcinomas have in common is the kind of cells from which they originate. Specifically, all carcinomas develop from epithelial tissue.
Neuroendocrine carcinoma is another type of carcinoma that occurs in the colon and rectum. Neuroendocrine carcinomas account for about four percent of all colorectal cancer.
