There are a number of habits that put us at greater risk of cancer — and almost as many things we can do to decrease that risk. 

But knowing what those habits are can be a bit more difficult, especially with new evidence coming in all the time clarifying what we know — and don't know — about those risks.

To help get a sense of what the public knows, the American Institute for Cancer Research surveyed about 1,000 people about whether or not certain factors had an effect on whether a person develops cancer.

In a new report out Wednesday, the AICR detailed the cancer risks Americans are good at identifying, the ones they're not so good at knowing, and the ones they tend to get wrong.
