Just an update incase anyone was curious.
I dont have breast cancer (thankfully!) the reason for the problems (shrinking breasts,aching,discharge and etc) was due to me losing a lot of weight in a short period of time.
But just want to echo what was said here, you can be any age and get breast cancer, its not just the "over 40s", I tried to explain this to the GP over and over again, (bit ironic that i was the one doing it!)
