A few weeks ago I noticed about a 1cm hard lump in my breast. I was unable to move it. I saw my ob who expressed concern and even noticed it couldn't be separated from the "tissue". She sent me off to get an ultra sound. Immediately the radiologist said it was my saline implant valve. It is just below my areola. implants are 7 years old, saline and under the muscle. I have never felt this before and can not find it feel a valve in my other breast. Does this seem accurate?
