Take-Home Message
- Patients with colon cancer have an increased risk of developing subsequent (metachronous) colorectal malignancies, especially in the presence of multiple polyps.
- Regular colonic surveillance and follow-up are essential for early detection.
- Synchronous and metachronous colon cancers may indicate an underlying familial or genetic predisposition, warranting genetic counseling and family screening.
