Could a burning sensation after passing urine be due to cancer?

I have burning before and after I pass urine, which started after I began having sex with my boyfriend. Could this be a sign that I have cancer, although all my tests have shown nothing?

If you have had lots of tests then it is likely that a cancer would have shown up during those tests. A burning sensation when passing urine is more usually due to a bladder infection. Both you and your boyfriend should have tests to check for infection. It is likely this may be cystitis which is inflammation of the bladder. 

Cystitis can be caused by infection, but burning can occur in women if the urethra has become bruised during sexual intercourse. If your burning is worse the day after sex and then gets gradually better until the next time, then that may be the cause. Your partner may need to be a little gentler, or you may need to experiment with different positions that do not cause you discomfort. 

A burning sensation when passing urine could be a symptom of bladder cancer, but this does not sound likely in your case. We have information about diagnosing bladder cancer in the bladder cancer section.

Talk to your doctor or practice nurse if you are still worried or if the burning continues.
