Hi There is such an avalanche of info out there. And you know after meeting so many people over my 15mths of treatment in the chemo ward none of the "causes of breast cancer"make much sense. The majority of women I've met were skinny minnys. There was sporty girls and not so sporty ones. There was low fat and high fat diets, (one even was very close to being a vegetarian,she had occassional chicken/fish). Many breast fed there children,, many led healthy lifestyles, few didn't drink alcohol at all, many social drinkers, all different nationalities. Way too many young women.!!!
The underwire bras? I thought they had disproved that as long as the wire was around your breast and not cutting in to it. So I would say make sure the bra is well fitted and most of all supporting and comfortable and go for it.
