hi dejaboo, left breast, upper outer quadrant, grew from about 1:00 down to the nipple, and pulled inward.

i am right handed, slept on stomach before, or left side, now sleep however, wherever works.

  Left inner lower quadrant,  IDC also closer to nipple then chest. Left handed, sleep on my left side.

I am finding this very interesting. The main IDC which is about 1.9cm is right behind the nipple on the right breast. We did not find it on the mammogram nor did i nor the drs which I went to several find it on an exam of the breast. It showed on the US. After MRI,found small speck of IDC also in the 50% quadrant. 2 others of benign on left breast on outter quadrants. I am ambidextrous,play golf with left hand but bowling and tennis with right hand. ROTC rifle with right hand but paint with left hand. Yep,Iam a mess,need to go back to Barbie factory for new boobs and brain. The original Barbie had no brain at all right..just an empty head? Back in the day when she had the oval eyes,I know the  new ones have round eyes. When I was a kid mine had Mattel stamped on her butt. But I digress..where do you find this stuff? I also like the studies from the Lancet and Oncology Journal on Medscape. Read the Warrior Goddess by Dr Christine Horner about bc research and currently reading Total Breast Health by Robin Kenuneke.

Lower outer, right and dominant side.

I alrady posted my stats on location: outer upper right.

 I am adding this info: I am right handed, sleep on the right side.
