Say you're a woman having a screening mammogram and the radiologist finds something suspicious. But it turns out to be a so-called "false-positive," and not any type of cancer. So you're off the hook. Right? Maybe not, because a new study says that result might have implications for developing cancer at a later time.

Most people have heard of SAD, or Seasonal Affective Disorder, which is a fancy term for depression that typically has its onset in late fall or early winter a period when the days are getting shorter. A study found that treatments involving exposure to light, as well as taking medication, showed promise in helping sufferers.

Ritalin, a staple for the treatment of ADHD in children, is the subject of a new Cochrane Report questioning its effectiveness. The review, which also contains caveats that somewhat undercut its primary finding, indicates that the widely-used drug may have a better reputation than it deserves.

Rather than taking AIDS medication prophylactically on a daily basis, it's now possible to use it the following day, a practice that still prevents infection quite well. While this is surprisingly good news, there are also downsides to this approach.

Just when we thought the increase in Type-2 diabetes would go unabated, new statistics published by the Centers for Disease Control and Prevention cast a glimmer of hope in what was an otherwise grim trend. The news was so eye-opening, even CDC researchers were surprised.

A new study using PET scans on the brains of older individuals shows a three-fold higher risk of mild cognitive impairment (MCI) among those with elevated levels of amyloid-beta, a proteinaceous material associated with neurodegeneration. MCI is a known risk factor for Alzheimer's disease.

The seasonal nature of the flu shot, as well as misinformation about its perceived toxins, have damaged the vaccine's public image and contributed to its perceived ineffectiveness. But as researchers attempt to come up with a long-lasting universal flu vaccine, a new study may have an answer as to why we are failing to develop it.

Women with relatively severe PMS may be at higher risk of developing high blood pressure (HBP), or hypertension. It's not clear how such an interaction may occur. Premenstrual syndrome sufferers may be at especially high risk of developing HBP before age 40. Thiamine and riboflavin may reduce the increased risk.

We're used to thinking that men typically drink more than women. That's still true but it may not continue to be so if current trends are an indication of future behaviors. Based on survey data, nearly half of all women reported consuming alcohol within the previous month, a finding which is up from 10 years earlier. Meanwhile, for men, tipping a drink, dipped.

Since 1965, U.S. births by cesarean section have increased seven fold, from 4.5 percent then to 32.2 percent of all deliveries in 2014.
