If the blood is red, then it just means the cancer is lower down - closer to rectum. If it's black, then it's higher up in the colon.
When I saw an internist to schedule a colonoscopy, he asked if I had any bleeding, and I said I did, but it was from my hemrroid.
He insisted on checking....and did an internal and said it was.
But he didn't do a biopsy to confirm....
Mine was from years of diarrhea - the constant wiping.
