Colon cancer can also be hereditary in some families, although the majority of cancers are not hereditary. We recommend that individuals consider genetic counseling if they have a personal and/or family history of any of the following:
1. Colon or endometrial cancer diagnosed before the age of 50.
2. Multiple relatives on the same side of the family with the same or related cancers (e.g. colon/uterine/ovarian)
3. More than one HNPCC cancer diagnosis in a single individual (e.g. colon and uterine, synchronous/metachronous colon cancers, colon and ovarian).
4. Individuals with greater than 15 gastrointestinal polyps, multiple polyposis or greater than 5 hamartomatous polyps.
5. Even one sebaceous carcinoma or adenoma.
6. Colon or endometrial cancer that has an abnormal MSI or IHC; or
7. Known genetic mutation in the family (HNPCC, FAP, etc.).
