I have a question. I ve been a little tired, along with some discomfort on both sides of my body- down where my stomach is (my stomach doesn t hurt, but around that same area on both sides, there is some discomfort), as well as I ve only been able to poop after a long period of sitting on the toilet for like an hour- more or less, I don t have that urging feeling to poop anymore, like when you have to go pee even though I still can go poop, and I ve had diarrhea/loose poop for more than a year, but I think that that has stopped now. Are any of these signs of cancer?
