I felt a lump and had a diagnostic mamm that showed tissue of both breasts to be heterogeneously dense but no abnormalities seen. They did an ultrasound in addition to the cyst which I felt, they found a 7mm hypoechoic mass, middle depth, BIRADS 4a. Now I'm kind of freaked out. If I squeeze the breast as opposed to pushing there's a hard area in the middle about the size of a golf ball. I kind of feel a similar but smaller area on the left (which they didn't us). Can it be something besides cancer? I am going to have a biopsy but I have to wait a week. If there's a high chance of being cancer a could go to a renowned cancer clinic but I would have to wait longer for the biopsy. Don't know what to do or think...
