Vitamin-D from UV exposure can reduce your risk of Breast Cancer by 60%
Vitamin D isn’t really a vitamin – it is a hormone your body produces naturally and most effectively when your skin is exposed to UVB in sunlight. That energy starts a chemical reaction in your skin which produces a form of vitamin D that your bloodstream carries to the rest of your body to be used.
For more than a century scientists only knew that modest levels of vitamin D were necessary for bone health. Vitamin D helps your body process calcium – the main building block for bones. No one knew that it actually does much more than this. For 50 years scientists have known that most forms of cancer were much less common in sunny areas of the world. But no one knew why.
In the late 1990s the story started to come into focus for the first time. That’s when scientists first discovered a new role for vitamin D: It controls and regulates cell growth in most systems in the body. But to perform this function people needed much higher vitamin D levels than had always been recommended – what we now call “Natural Vitamin D Levels.” Without artificial supplements, it now appears the new vitamin D levels are only naturally possible with regular exposure to UVB in sunlight.
That discovery in the late 1990s spawned hundreds of subsequent studies into vitamin D and reduced cancer risk – including breast cancer. The research has boomed in the past three years:
•A 2006 paper published in Anticancer Research established that women with higher vitamin D levels are 50-70 percent less likely to develop breast cancer.
