My BC was in the cranky breast--the left-- that I had trouble feeding with. The nipple inverted a bit during pregnancy and it was always painful and difficult which lead to cracked nipples and mastitis. I've got lobular carcinoma which is different from ductal in the way it presents. My original tumour was very high up on my chest and while still in breast tissue, it didn't seem to have much to do with the nipple or the tissue surrounding it.
It was a long time between breast feeding and cancer, but I have often wondered if there was any correlation given that tit would not behave itself.
