Elevated hormone levels add up to increased breast cancer risk

Post-menopausal women with high hormone levels, including estrogen and testosterone, have a higher risk of breast cancer. Researchers found that each additional elevated hormone level increases risk by 16%. The study suggests that models assessing breast cancer risk could be improved by considering multiple hormone levels.

Acid-suppressing medications may be overprescribed for infants

Dr. Eric Hassall cautions against over-diagnosis of gastroesophageal reflux disease (GERD) in infants under one year old, as most symptoms can be attributed to physiological reflux or normal developmental phenomena. Non-pharmacological measures such as dietary changes and reassurance are often sufficient to resolve the issue.
