Familial Adenomatous Polyposis (FAP)

Familial Adenomatous Polyposis (FAP) is a rare genetic condition which may present with various and differing symptoms but always including the presence of multiple polyps in the colon. These polyps will, in time, become cancerous.

Polyps increase in number from mid teens onwards, eventually developing into cancerous cells. If the condition is not recognised and monitored, anyone with the condition is certain to develop colorectal cancer. It is possible that someone with FAP will not know of any relatives in recent generations with the condition but it can be confirmed through genetic testing. If any first degree relative (parent/sibling) has FAP or if bowel cancer has occurred at an early age in a number of individuals in recent generations,  you should ask your GP to refer you for genetic testing. If the test confirms that you are carrying the genetic mutation, your health can be monitored and any cancer or precancerous polyps will be detected and treated at an early stage. People with FAP also have an increased risk of developing various other cancers in other organs.

People with FAP require frequent monitoring by colonoscopy. If you live in Surrey or surrounding counties, the GUTS Colon Cancer Family Clinic may be able to offer support.
