Familial adenomatous polyposis (FAP) is an uncommon hereditary disease characterized by the appearance of more than one hundred benign polyps in the colon and rectum after the second decade of life. The problem is that, once over thirty, the risk that any of these polyps will become malignant is very high, to the point that those affected by PAF have a risk close to 100% of developing colorectal cancer at some point of his life unless he undergoes colectomy - removal of the colon.

However, the likelihood of developing polyps in the duodenum is also very high. In fact, 15% of patients end up developing small bowel cancer. Más información
