I have bumps that prolapse after every bowel movement. I looked and they don't look the same. One is white and the other is flesh-like. Kinda looks like a berry. They started as one small bump that I could feel with a finger after seeing blood in my stool. They multiplied very fast. They're now not growing only color changes. I saw a doc and he said he believes it's polyps. He recommended a colonoscopy and casually mentioned cancer and now I'm freaking out. Any different opinion?
