Hi, When I was 25 I found a lump in my rat breast, it was benign, I have since had a mammogram yearly, I am now 43. I have noticed a change in my right breast. It s about 11 o clock near maybe 2 inches from my armpit. My recent ultrasound was negative. 7 yrs ago I was called back for a second mammogram due to high density of my breast, further testing then showed nothing. I am concerned, my family history of breast cancer is extensive, from my grandmother and 2 of my 4 aunts and 3 other females 1st cousins all diagnosed before age 40, I m not sure what do do, I ve been insistent with my doctor, but the test show nothing, but I know it s something going on even if it isn t cancer. Any advice?
