I spoke with my Mom again today about her upcoming colonoscopy. She's worried about it and I am as well but I realize that the occult blood could be many different things. She has hemorrhoids and I told her that they could be the cause of it and she said that's what she thought too, but that blood would show up as bright red. The doctor had her redo her stool test after there was blood found on the first one and then there was blood again on the second one. She said she was sure she was careful not to have hemorrhoid blood on the sample, but how can you NOT if you have hemorrhoids? I mean the stool is going to pass over them regardless right?
She kept telling me over again that it wasn't hemorrhoid blood, but even the tiniest amount could mix in and not be seen by the naked eye, couldn't it?
