I was diagnosed with FAP when I was 28. Hundreds of adenomas polyps were found all over the large intestine. My only symptom was rectal bleeding. No one in my family had or has FAP but me. A year later, it went to thousands of polyps in the large intestine, so my GI doctor referred me to a colorectal surgeon and told me I needed colorectal ileo-anal surgery then. He said if I didn’t have the surgery before I was 30, I would die before I was 40. I didn’t start growing polyps in my rectal stump or duodenum until 14 years ago. They are removed every year and more grow then they are removed.
