question: Hello Ive been experiencing some on and off pain in my lower right abdomen! Not heavily painful but enough to be annoying, with this pain I occasionally experience blood in the urine that I can clearly see Ive been to the doctor and they have said it may be a kidney stone or benign Ive had x rays and there was no signs of either Im starting to get really worried and have been reading up on information and thinking its bladder cancer if you can tell me anything it would be greatly appreciated thanks
