I am sorry to hear about your problem and I realize it is a sensitive topic. The bright red bleeding is most likely caused by hemorrhoids. I am a nursing student who has seen colonoscopies performed and they will detect cancer pretty clearly. The fact that you have already had 2 done tells me you most likely do not have cancer despite the findings of polyps.
Polyps are simply extra tissue that grows inside your colon. Most polyps are not dangerous. Most are benign, which means they are not cancer. But over time, some types of polyps can turn into cancer. Usually, polyps that are smaller than a pea aren't harmful. But larger polyps could someday become cancer or may already be cancer. To be safe, doctors remove all polyps and test them.
So ask your doctor if he has found any evidence of hemorrhoids during your previous colonoscopies and chances are that is your bleeding problem. Good luck to you!

I am sorry that you are going through this. I will say a prayer for you. Sorry to say, it doesn't sound good.
But, lets hope for the best.
Take care.
