Anastrozole Effective at Reducing Long-Term Breast Cancer Risk

Tamoxifen has been known to be an effective drug to reduce risk of breast cancer in high-risk women.

Anastrozole has fewer long-term side effects than tamoxifen; however, does anastrozole protect women past the five-year treatment completion? Researchers continued ...

The Deadly Consequences of Fine Particle Air Pollution

A new study finds an association between fine particulate matter (PM2.5) air pollution and deaths from nine different causes, including cardiovascular disease, cerebrovascular disease, hypertension, dementia, and lung cancer, among others. Furthermore, 99% of PM2.5-associated deaths were linked to levels of PM2.5 exposure currently deemed acceptable by US Environmental Protection Agency (EPA) recommendations.Atmospheric particulate matter with a diameter of less than 2.5 micrometers, PM2.5, is p...
