Risk of thyroid cancer among Caribbean Hispanic patients with familial adenomatous polyposis.

Familial adenomatous polyposis (FAP) is an inherited form of colorectal cancer characterized by hundreds of adenomatous polyps in the colon and rectum. FAP is also associated with thyroid cancer (TC), but the lifetime risk is still unclear. This study reports the standardized incidence ratio (SIR) of TC in Hispanic FAP patients.
