Over 500,000 people died from cancer last year, yet over half of them could have been prevented, according to a new review article in Science Translational Medicine. There are multiple ways that some cancers can be prevented. Here are a few:

1 – Don’t smoke. If you do, quit. It may be hard, but more than 75% of lung cancer cases could be avoided in the U.S. if people didn’t smoke.

2 – Ask your healthcare provider about vaccines for HPV and hepatitis, which can cut liver and cervical cancer rates in half.

3 – Get more exercise and drink less alcohol to decrease breast cancer risk.

The authors of the article also pointed out that studies should be done with a younger age group since lifestyle choices made early in life can impact cancer risk later. Study participants are usually followed for a few years, but in order to see long term effects, the authors suggest participants should be followed for much longer.
