Sex hormones hold key to higher rates of abdominal aortic aneurysms in males
...ies in male sex hormones. They found that removing circulating
androgens, including testosterone and dihydrotestosterone, from male mice lowers their risk of aneurysm to that of females, while giving females these same male sex hormones increases their risk to that of males. Tracy Henriques, a graduate student i...

Obesity is risk factor for aggressive prostate cancer
...e, fat makes estrogen-like compounds, which lowers circulating
levels of prostate specific antigen, or PSA, a marker for prostate cancer. If PSA levels are lower due to hormone changes from obesity, the prostate cancer is less likely to be detected at an early stage. Hormone changes observed with obesity also c...
Physical activity associated with improved survival for women with breast cancer
...ysical activity has been linked to lower levels of circulating
ovarian hormones, which may explain the relationship between physical activity and breast cancer. Lower estrogen levels among physically active women with breast cancer could potentially improve survival, although few data exist to support this hypot...
