An adenoma is a non-cancerous lump that starts in gland tissue. It can grow in places like the colon, liver, kidneys, or pituitary gland..
He reviews your personal and family history of polyps or cancer, lifestyle habits, and any symptoms like blood in the stool or headaches.
We check complete blood counts, liver function, and pituitary hormone levels (if a pituitary adenoma is suspected) to rule out other conditions.
A colonoscopy (or upper endoscopy) allows direct visualization and removal of small polyps. Biopsies are taken to determine the exact cell type.
Biopsy samples are analyzed by a pathologist to confirm adenoma subtype (e.g., tubular, sessile serrated) and assess any dysplasia.

An adenoma is a non-cancerous lump that starts in gland tissue. While initially harmless, some types can grow or turn cancerous if not removed.
A tubular adenoma is a common colon polyp made of tube-shaped cells. It's benign but can develop into cancer over time if left in place.
A sessile serrated adenoma is a flat, broad-based polyp in the colon with a saw-tooth pattern. Removal is recommended to reduce cancer risk.
The ICD-10 code for a benign pituitary adenoma is D35.2. This code is used for medical records and insurance billing.
Yes. Some adenomas especially in the colon may transform into cancer if they're not detected and removed early.
