Lifestyle Changes That May Help Prevent Cancer

Font Size

Topic Overview

Experts believe that one-third to one-half of all cancers can be prevented.

That's because there are certain things about our lifestyles-our daily habits-that can make us more likely to get cancer. Here are some steps you can take today to help prevent cancer:

Did You Know?

Under the Affordable Care Act, many health insurance plans will cover preventive care services, including checkups, vaccinations and screening tests, at no cost to you. Learn more.

  1. Quit smoking.
  2. Eat well.
  3. Stay at a healthy weight.
  4. Stay active.
  5. Protect your skin.
  6. Drink alcohol wisely.
  7. Practice safer sex.
  8. Get regular checkups and screenings.
  9. Consider getting the HPV vaccine if you're age 26 or younger.
  10. Avoid toxins and other poisons at work and at home.

Your doctor may recommend other things based on your personal health history. For example, taking aspirin to prevent cancer may be a good idea for some people. But taking aspirin can have risks, too. So talk to your doctor about what cancer prevention tips are best for you.

Quit smoking

When you quit smoking, you lower your chances of getting many types of cancer. Smoking makes you more likely to get cancers of the lung, bladder, kidneys, pancreas, cervix, mouth, esophagus, and throat.

Quitting is hard, but you can do it with the right amount of information and support. And there are several medicines that work well to help people quit for good. For information, see the topic Quitting Smoking.

Eat well

Eating a variety of vegetables, fruits, legumes (for example, peas and beans), fish, poultry, and whole grains helps prevent cancer. Limit the amount of fat in your diet, especially animal fat.

Some scientists think certain supplements might help prevent cancer, but there isn't enough research yet to prove that. If you want to take supplements to prevent cancer, talk to your doctor about what is safe for you to take. Eating healthy foods is still the best way to get the vitamins and minerals your body needs.
