Cancer threat estimation
The Harvard Center for Cancer Prevention has put up an website-tool to estimate your risk of cancer and provides personalized tips for prevention.
It doesn't tell you if you'll get cancer or not. Anyone can use Your Cancer Risk, but it's most accurate for people age 40 and over who have never had any type of cancer.
I agree to the statement "the best way to fight cancer is to keep it from starting". So act now before its too late.
