Here's a list you'll want to check twice: Five ways to slash your risk of cancer.
Doing just one of the anticancer steps is better than nothing. But do all of them and you're cancer risk could drop by as much as 30 percent.
1. Don't smoke (a no-brainer).
2. Limit red meat, alcohol, fat, and salt.
3. Eat fruit, veggies, and whole grains -- lots of them!
4. Exercise regularly.
5. Watch your weight.
Although there is no surefire way to prevent cancer, making healthy choices in your daily life may reduce your risk. If you don't feel capable of following all the anticancer guidelines, at least choose to do the ones you know you have a good shot of sticking to. You can add a few more later, once you've made some progress.
