What is the life expectancy of someone with Familial Adenomatous Polyposis?

Depends on care recieved

It varies on when diagnosed

Thanks to modern medicine the life expectancy of someone with FAP is not shorter than someone without it.

I am 62 and have FAP, Diagnosed in 1990, I have a J pouch. I have yearly endoscopies to look for polyps. Each year they find more but we are keeping on top of them. I will soon be swollening a camera to look for more in my small intestine. The problem with Fap is that cancer will show up in other parts of the body. I had a tumor cut out of the bile cut of my pancreas, it was pre=cancer and the specialist said it would have killed me in a couple of years. Tumors removed from my jaws 3 times, Eventually losing all my teeth. Mastist in my right breast off and on for ten years. In March 2018 I was diagnosed with breast cancer in my right breast and had a mastectomy. I keep fighting. I will see this through and come out the other side. Have faith in yourself and the doctors treating you. Jackie Martin
