Perspective on alcohol use and cancer risk

There seems to be general agreement that, for most people, moderate alcohol use isn’t particularly harmful to health. At the same time, some people have seen the negative effects of alcohol up close and personal. A new study makes alcohol seem even more controversial, suggesting that there is sufficient evidence to say that alcohol causes several types of cancer.

Researchers believe that a non-invasive screening test that can identify genetic markers for high-grade prostate cancer in urine may eventually reduce the number of prostate biopsies needed.

News that mosquitoes in the U.S. carry Zika is concerning, but experts say that Zika likely won’t spread here as it has in Central and South America. The virus poses a danger to pregnant women and their unborn children because Zika may cause microcephaly, a birth defect in which a baby’s head is unusually small and the brain does not develop properly. The CDC warns pregnant women, or those trying to become pregnant, to avoid areas with high rates of Zika infection, and warns all travelers to such areas to take certain precautions.

Fentanyl: The dangers of this potent “man-made” opioid

Fentanyl is a powerful synthetic opioid. It is far more potent — and potentially more dangerous — than heroin and morphine. Overdose deaths related to fentanyl are on the rise. The drug is cheaper than heroin and recently is being used to dilute heroin or substitute for it. Users may be unaware that they are taking this potent drug, or may even seek its intense high. People at risk from using fentanyl can be treated successfully with therapies used for other opioid use disorders, but taking steps to prevent overdose are critical until a person is ready to seek care.
