Nenemiles, I had my first mammo at about 37 but only because my Mum had BC at 40, I have no other family history, I did get BC but not until I was 43 and again at 47. Absolutely I'd get a Mammo and ultrasound just to rule it out and so you know whats going on. I had no lump nothing at first diagnosis, however my second the BC developed in my scar tissue from my lumpectomy 4yrs prior. I had cysts that come and go, but honestly do get it all checked out for peace of mind. Hugs Melinda xo
