I am 20 years old and super confused. My grandpa and aunt had colon cancer (stage 1 and were fine after surgery- no radiation needed). I get a strong stomach cramp sometimes when peeing and for the last 2 months or so when I go poop I bleed. Before it was just a little here and there but recently the toilet is red with tiny clots. I went to my doctor who ordered a colonoscopy and said I definitely have colon cancer and it is likely advanced. I haven’t even had the colonoscopy yet! Can you have colon cancer with little to no symptoms?
