All my life, but then genetically speaking no member in my family has had FAP. I would assume that my inherent risk is low, unless the tales of mother and the milkman are actually true....
Familial adenomatous polyposis. Mind it is genetic and if you have FAP in your family tree then I strongly suggest you get to a doctor for regular exams.
While onset of FAP in purperty is non-cancerous polyps, around age 39 the rists of cancerous even malignancy increases.
Trust me, you don't want cancer of the large intestine (colon) and rectum.
