<human>: Hi, There is blood in my urine. Checked the prostate and it was fine, have an ultrasound in a couple of days for kidneys, and bladder . Since I have been told I have blood in my urine, sometimes, I have a burning sensation after urination , what is the percentage that I might have bladder or kidney cancer , knowing that since I was a kid, I suffered from kidney stones?
<bot>: Hi Tom, burning sensation and blood in your urine may be caused by many diseases such as kidney stone and infection, prostatitis, rhabdomylosis and also kidney cancer. But most of our patients with that symptoms cause by infection and kidney stone.  For kidney cancer, statistically about 1.2 % men and woman born today will be diagnosed with kidney cancer, These statistics are called "the lifetime risk of developing kidney cancer as you can see at http://cancer.emedtv.com/kidney-cancer/kidney-cancer-statistics-p3.html. So you must be aware but not to be panic.  What you should check is beside burning sensation and blood in your urine, is there any other symptom like you may feel back pain, weight lose more than 5%, flank pain, and swelling or enlargement of the abdomen.  If you had symptom above or want to do health screening, go to consult with urologist to do MRI, blood and urine test for more accurate diagnosis. Hopefully this will answer your question. Thank you
