... outer quadrant. My right breast does not have this thickening. Went to the dr. and she felt it as well and referred me for a mammogram. Radiologist felt and saw it on the scan. Us technician saw it on the u/s. Dr. on duty said it looks the same as my mammo last year, but I know my breast feels different than last year. My question is this, since I have lost about 12 pounds, (and gone down almost a size in my bra) could this have been there all along and I didn't feel it? Or should I ask for a second opinion? The Mammography doc says it's just dense tissue. I'm just not convinced
