I just returned from an appointment and discovered that I too have the same thing. My doctor is suggesting the wait and see. I have only known about my lump for a few months ( I wasn't diligent about checking for quite some time before that). To me it seems like it has gotten bigger in this short time, but how does one really know for sure?? On the ultrasound it measured 7mm x 7mm x 3mm. From the outside feeling in - lol! it feels way bigger today. I know mine is really tiny, but I still would like it out. How big do they need to be before they will do a biopsy?
