Not sure if anybody else heard about this, but there was an extremely intriguing research report and analysis released last month that suggests (lack of) Vitamin D and it's related pro-forms (D2, D3, D4, etc.) has a very high correlation to increased risk for several cancers. Specifically, this report showed that, of a study of 1200 women, there was a 60% reduction in the appearance of cancer in subjects taking Vitamin D supplements compared to those not taking supplements. I believe I heard on NPR news that this 60% difference is actually a higher level of difference between similar cancer-rate studies comparing people who smoke to those that do not. Interesting to say the least.
Anyhow, I was reading up about it (again, because I'm supposed to be working on a data set... and we all know that frequent breaks help facilitate brilliance and creative thinking) and found another, older, but interesting article about how cancer patients respond much better in the summer
than winter following cancer procedures, presumably because the increased sun exposure in the summer allows the body to more easily create higher levels of the 'activated' forms of Vitamin D, which (might? probably?) act as an anti-cancer agent.
Might be time to start taking some D Vitamin supplements.
