I've had fibrocystic breasts since the age of 11. Mammo's since then too. One abnormal mammo five years ago, lumps still there, too little to biopsy. I wear a bra 24/7 because going without one hurts so bad. THEN I see this report on the TV. Great, wouldn't you know they say it's not a proven thing but those who wear bras 24/7 are at a greater risk? Yeah! Of course as I took off my bra Jim was smiling.
