Re: Male breast cancer??? Or health anxiety gone too far?
The chances of it being breat cancer are low to be honest, espcially if it was a secondary - you would be very ill by now and the cancer would have invaded the circulation in order to spread. Cellular-wise, the testicles and chest are a long way to travel! The sharp pain isn't typical of cancer pain, which usually causes pain by pressing against tissues or invading healthy tissue.
All you can really do is follow the GP's advice and been seen if it gets worse.
