[|Human|] 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
[|AI|]  Hi! Thank you for your question. Personally and professionally, I am also leaning towards a kidney stone or a benign lesion. Urinary bladder carcinoma occurs very rarely (4 for every 100,000 in men and 1 for every 1000 in women) and is commonly diagnosed in individuals over 40 years (median age of diagnosis is 65 years). The most common presenting symptoms are microscopic hematuria (blood only seen when a urine sample is placed under the microscope) and frequent urination. On the other hand, gross hematuria (visible blood in the urine) commonly is a sign of a stone - which may or may not be seen in x-rays. There are stones that are too small to be detected by x-rays or are made up of substances that make them invisible to x-rays. I would suggest that, through a urologist, you undergo other and more sensitive tests: ultrasound or CT scan/MRI. Take care and I hope you feel better soon! Please do not hesitate to contact me for further queries.
