Prostate cancer in transgender women
The transgender population is steadily increasing. Last year, investigators reported that 1.3% of people between the ages of 18 and 24 in the United States identify as transgender, compared to 0.55% of the country’s older adults. This trend has implications for public health, and one issue in particular concerns the risk of prostate cancer in […]
Why eat lower on the seafood chain?
Many health-conscious consumers have already cut back on hamburgers, steaks, and deli meats, often by swapping in poultry or seafood. Those protein sources are better than beef, and not just because they’re linked to a lower risk of heart disease, diabetes, and cancer.

Should a woman consider having her fallopian tubes removed to lower her risk for developing ovarian cancer?

Curbing nearsightedness in children: Can outdoor time help?
Turns out that when your mother told you to stop sitting near the TV or you might need glasses, she was onto something. Myopia, or nearsightedness, is a growing problem worldwide. While a nearsighted child can see close objects clearly, more distant objects look blurry. Part of this growing problem, according to experts, is that […]
Is alcohol and weight loss surgery a risky combination?
For people with obesity, weight-loss surgery can reverse or greatly improve many serious health issues, such as diabetes, high blood pressure, and pain. But these procedures also change how the body metabolizes alcohol, leaving people more likely to develop an alcohol use disorder. A new study finds that one type of surgery, gastric bypass, may […]
Will miscarriage care remain available?
When you first learned the facts about pregnancy — from a parent, perhaps, or a friend — you probably didn’t learn that up to one in three ends in a miscarriage. What causes miscarriage?
