Sunlight Fights Cancer
Wait, sufficient sun exposure helps prevent disease—NO—you don’t say? Pardon my smart-alecky tone, but this factoid is an old hat for DiseaseProof. Let’s review. Alright, remember this report, Sunlight in Youth Might Shield Against MS? Here’s a refresher:
"Evidence is building up that something in relation to sunlight and/or vitamin D exposure during childhood may play a protective role," said study co-author Dr. Thomas M. Mack, of the department of preventive medicine, Keck School of Medicine, University of Southern California, Los Angeles. "It's now been suggested by several different studies that this is the case, and if it's true, it would be important."Okay, okay. That’s Multiple Sclerosis, but what about cancer? Is it possible that something as simple as basking in the sun can reduce our risk of developing something as insidious as CANCER? More learning tree time, remember Ultraviolet: Go into the Light? Take a look:
In two studies with mice, a British team cloaked antibodies -- the immune system proteins that tag germs and cancer cells for elimination -- with an organic oil that blocked them from reacting until illuminated with ultraviolet light.Still not convinced? Alright, I’ve got a new report for you. Amanda Gardner of HealthDay News brings this to the table, under the catchy title, Sunlight Helps Put Lung Cancer in the Shade. Lung cancer too? Yup, lung cancer too! For real, from the report:
The researchers used engineered immune system proteins called monoclonal antibodies. They are made to home in on proteins known to be overactive in tumor cells.
When the light unblocked the organic coating, the antibodies switched on and attracted killer T-cells to attack the tumor, said Colin Self, a researcher at Newcastle University, who led the studies.
A new study finds that lower levels of the sun's ultraviolet B (UVB) rays are associated with a higher incidence of lung cancer across 111 countries.“For over 60 years, researchers have observed an inverse association between sun exposure and cancer mortality,” explains Dr. Fuhrman,” And those with more sun exposure had fewer cancers.” See, not exactly new news, but how many people listen? That’s the question!
Still, that doesn't mean that spending more time in the sun will ever offset the risks that come with smoking, according to the study, which is published in the January issue of the Journal of Epidemiology and Community Health.
It's also not an excuse to trade skin cancer for lung cancer.
"The problem is that people might over-interpret this and stay in the sun for hours," said Cedric Garland, study senior author, professor of family and preventive medicine at the University of California, San Diego (UCSD), and participating member at the Moores UCSD Cancer Center in La Jolla.
