small cell carcinoma

(... sel KAR-sih-NOH-muh)
A fast-growing type of cancer that usually occurs in the lungs but may also occur in many other parts of the body, such as the cervix, ovary, bladder, prostate, liver, pancreas, and stomach.

Small cell carcinoma tends to spread quickly to other parts of the body and usually has a poor prognosis (chance of recovery). Also called oat cell cancer.
