Sustained weight loss linked to reduced breast cancer risk

A new study conducted by the American Cancer Society shows that sustained weight loss in women 50 years of age and older and not using postmenopausal hormones had significantly reduced levels of breast cancer risk.  According to study findings on 180,000 women 50 and older, women who lost 2-4.5 kg had a 13% lower risk of developing cancer, while those losing 4.5-9 kg saw the risk fall to 16%, and women losing 9 kg or more had a 26% lower risk.

Breast cancer subtype incidence in men differs from trends in women

A new study conducted by the American Cancer Society indicates that "incidence rates for hormone receptor (HR+) breast cancers are considerably higher in black men than white men, in stark contrast to lower incidence rates of those cancer subtypes in black versus white women." The study is unique as it is the first report studying rates of breast cancer racially and gender.  Findings indicate a 41% higher incidence for HR+/HER- breast cancers, 65% higher for HR+/HER2+,  among black men.
