We're all grown-ups here — nightmares aren't a big problem anymore. We're calm, we're cool, we're mostly collected ... until it comes to the C-word. For adults, cancer is the thing that goes bump in the night, and that bump gets louder when family or friends are diagnosed. Whether your risk is monumental or blessedly average, you want to protect yourself. Here are 30 cutting-edge strategies to help keep you safe.

Worship a wee bit of sun. People who get the most vitamin D, which lies dormant in skin until ultraviolet rays activate it, may protect themselves from a variety of cancers, including non-Hodgkin's lymphoma, breast, and colon. Ironically, it even improves survival rates of melanoma, the most serious skin cancer. But 10 to 15 minutes a few days a week is all it takes to benefit. (Or you could try a supplement — aim for 400 IU a day.) If you're out any longer than that, slather on the sunscreen.
