Two studies show that fewer men have been screened for prostate cancer using the PSA test since 2012, when a federal panel advised against routine screenings. With doctors increasingly questioning the test's validity, that's a good thing. But the real key is whether reduction in PSA testing has led to a rise in late-stage or fatal prostate cancer.

At long last, the FDA approved biotech salmon, AquaAdvantage, which is bred to grow to twice the size of other fish. But in contrast to every scientific study and advisory, the editorial board of The New York Times writes that the genetically-modified fish should be labelled. We take issue with that position.

Metformin has long been the front runner of oral medications prescribed for glucose control in Type-2 diabetics. But could it also help adolescents with Type 1? Apparently not, as a recent JAMA study failed to find any statistically-significant benefit in improving blood sugar control.

New reports on breast cancer treatments are coming to the fore. One report finds that too many women are still receiving total mastectomies, when lumpectomy would suffice.

People tend to fear what they don't understand, and cannot control. And that adds to the apprehension people have when evaluating the safety of food produced using genetically modified organisms.

Like the use of luminol in crime scene investigations, researchers at Duke University, in collaboration with MIT in Boston, have developed a chemical dye that emits brighter fluorescence in cancer cells than normal tissue. The innovation could lead to better surgical results, by preventing subsequent operations.

With no topic beyond reach of his scorn, Donald Trump takes a shot at the NFL, calling the game "too soft" for its attempts to protect players with rule changes.
