This is a short article from Health Day about a recent study suggesting the weight loss, even 5% of body weight, reduced by as much as half the risk of developing estrogen positive (ER positive) breast cancers. Although this research was directed at women who had not been diagnosed, it is not a huge leap (at least for us non scientists) to wonder if the same thing might be true for reducing recurrence risk. Since we all know, and I have been hammering it in, that exercise and weight maintenance, if not actual loss, seem to reduce recurrence risk, this is another piece of information that helps us understand the possible reasons.

"Weight loss represents an additional option for long-term breast cancer risk reduction without significant or bothersome side effects," McTiernan added.
