FAQ
Frequently Asked Questions
No, an adenoma is by definition a benign (non-cancerous) tumor. However, some adenomas have the potential to transform into carcinomas over time, which is why they are often monitored or removed.
A polyp is a general descriptive term for a growth that protrudes from a mucous membrane. An adenoma is a specific histological type of polyp that is neoplastic and glandular. All adenomas in the colon are polyps, but not all polyps are adenomas.
Common sites include the colon and rectum (colorectal adenoma), the pituitary gland (pituitary adenoma), the thyroid (thyroid adenoma), the adrenal glands (adrenocortical adenoma), and the liver (hepatic adenoma).
It comes from Greek: 'aden-' (ἀδήν, adēn) meaning 'gland' + '-oma' (-ωμα) meaning 'tumor' or 'swelling'. Thus, it literally means 'gland tumor'.
