Up to 1/3 of breast cancer cases in Western countries could be avoided if women ate less and exercised more, researchers at a breast cancer conference said. Experts said the focus should shift to changing behaviours like diet and physical activity. Obese women are up to 60% more likely to develop any cancer that normal-weight women. Many breast cancers are fueled by oestrogen, a hormone produced in fat tissue. So experts suspect that the fatter a women is, the more oestrogen she's likely to produce, which could in turn spark breast cancer.
