What are other forms of inherited colorectal cancer?

ANSWER

There are other, very rare forms of inherited polyposis syndromes that are associated with an increased risk of colorectal cancer. These include:

  • Juvenile polyposis (JP). Patients may have anywhere from five to 500 polyps, or growths, mostly in the colon and rectum, which usually begins before the age of 10. The stomach and small intestine are less commonly affected. These patients are also at increased risk of bowel cancer.
  • Peutz-Jehgers syndrome (PJS). Patients with PJS typically develop dozens to thousands of benign polyps, or growths, in the stomach and intestines, primarily in the small intestine. The growths can become malignant or can cause obstruction of the bowel.
