I was diagnosed with multiple breast fibroadenomas in my early 30’s I’m now 49 and found one of the lumps has grown a lot. I’m not sure if it’s because I have been weight training, running and cycling and lost weight and my breast have gotten smaller that I noticed it while lying in the bath a could see it or I should be really worried that it has become something more sinister. Will call GP tomorrow but my surgery is awful and worrried I won’t see someone. Anyone had any problems with fibroadenomas turning sinister?
