My biological mother died from colon cancer. She went quick.
A couple years ago I had a bleeding issue and my gastro strongly recommended having a colonoscopy due to my family history. I was 36 then. Everything that is said about the prep is true. At one point that foul drink made me sick and I projectile vomited. Felt lightheaded and dizzy the entire day before due to not being allowed to eat anything.
I came out of it with muscle strains in my neck and arm from the way they positioned me on the table after I was asleep. The test was all clear save for hemorrhoids. I don’t have to get another one until I’m 50 or if another problem comes up before then.
