When you go to your dentist for a filling, a syrupy substance will be inserted into the crevices of your molars. This coating will harden and will prevent bacteria from decaying your teeth.

The fifth edition of the State of the Evidencereport from the Breast Cancer Fund was just released. It finds that exposure over time to synthetic chemicals, such as hormone and endocrine-disruptors, found in plastics, cosmetics, cleaning products, food, and other consumer products, increase the risk of breast cancer. Other sources and factors, such as occupational exposures to hazardous chemicals are also identified as playing a role in breast cancer.
