Medical Notes: Week of July 15, 2018

When it comes to cancer are you better off safe than sorry? Despite cancer screening’s potential risks, many Americans still want it. A study in the Journal of Experimental Psychology finds that more than a third of participants want to receive a hypothetical cancer screening, even when the possibility of serious harm is described in detail. Clinicians say screenings can produce false positives that could lead to unnecessary worry and follow up tests. They can also over-diagnose, resulting in costly and unnecessary treatment of cancers that will never spread.

Men who take low dose aspirin to ward off heart attacks have more reason to stay out of the sun. A study in the Journal of the American Academy of Dermatology finds those who take aspirin have nearly double the risk of developing melanoma compared to men who don’t take it. However, scientists say that’s no reason to stop taking aspirin, which not only reduces heart attacks but also helps prevent a variety of cancers. Women taking aspirin showed no increased melanoma risk.

And finally… want to get more done at work? Scoot on over to a window. A study from Cornell University finds that natural light produces health benefits and increased productivity. Lack of daylight and access to views decrease the ability of the eye to relax and recover from fatigue, but natural light cuts eyestrain is by 51 percent and reduces computer vision syndrome which impacts 70 million workers worldwide.
