Some facts about FAP:
-If FAP runs in the family, children should undergo screening for a genetic mutation
-Colonoscopies should begin as early as the age of 10 or 12 years old and repeated every 6 to 12 months
-When numerous polyps are found, colon removal (and sometimes rectum) is necessary because the polyps will become malignant
-Because the abnormal gene that causes FAP is present in all cells in the body, other organs such as the skin, bones, eyes, thyroid, and abdomen may develop growths
-At-risk family members should consider having their blood analyzed for the FAP mutation
-About 30 percent of individuals affected by FAP have no family history. The mutation occurred at conception. However, they may pass the gene to their children.
