The American Cancer Society (ACS) National Cancer Control Blueprint is a series of papers published in CA: A Cancer Journal for Clinicians. The goal of these papers is to describe evidence that will support creating a cancer control plan for the United States and putting the plan into action. This is the third story on cancer.org about the ACS Blueprint. The first story was about the blueprint’s goals. The second was about how well cancer control is working in the US.
Being active with your family will likely create more fun memories than one more night watching TV. As you instill healthy habits, all of you could be reducing your risk factors for cancer.
Editor’s Note: Guidelines on diet and physical activity are updated as scientific evidence continues to evolve. Please read the most recent recommendations here.
Some people may feel helpless against cancer and think they’ll only be able to conquer that fear when a cure is found. In fact, you may be able to lower your chance of getting many types of cancer. The ACS Cancer Prevention Blueprint describes what we know about risk factors for cancer that can be controlled. It also outlines cancer prevention strategies proven to help people avoid those risk factors. These strategies include choices each person can try to lower their risks for certain cancers. They also include actions and health policies that can be made at the city, state, and local community levels.
Controllable, or modifiable, risk factors are those that people can try to change by making healthier choices, like exercising more and drinking less alcohol. “Adopting a healthy lifestyle and sticking with it may help reduce your risk of getting cancer,” says Susan Gapstur, PhD, MPH. She’s the lead co-author of the Cancer Prevention Blueprint. Gapstur is a Senior Vice President at the ACS.
Using tobacco is still the leading cause of cancer. It’s also the most preventable cause of death from cancer. The blueprint notes that one of the most effective ways to reduce tobacco use is by raising taxes on tobacco products. When they cost more, fewer people (especially young people) may start to smoke. People may smoke less or even quit, and people who don't smoke may be exposed to less secondhand smoke.
The prevention blueprint urges everyone to follow this advice.
Smoking also leads to many other chronic diseases. They include breathing problems such as asthma and chronic obstructive pulmonary disease (COPD), heart disease, type 2 diabetes, stroke, and even eye problems that can result in blindness. “People who don’t smoke are much less likely to get these diseases,” Drope says.
Many people don’t realize that alcohol is a risk factor for cancer. “Drinking even small amounts of alcohol increases your chance for getting certain types of cancer” says Gapstur. In fact, ACS researchers found about 16% of all breast cancers are caused by alcohol use.
If you choose to drink alcoholic beverages, the ACS recommends.
If you have trouble limiting alcohol, get help from your doctor. Ask about treatment and support groups or counseling. The online tool NIAAA Alcohol Treatment Navigator from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) may also help.
Just as with tobacco, raising taxes on alcohol reduces the amount that people drink. “Studies show that a higher price for alcohol has other benefits too. It also reduces motor vehicle crashes and violence,” Gapstur says.
Researchers have shown that being overweight or obese can cause 13 types of cancers. For some cancers, the risk is very high. For instance, being overweight or obese causes as much as 60% of endometrial cancers.
Being overweight or obese can increase your risk for getting cancer in many ways. One of the main ways is that excess weight causes the body to make and circulate more estrogen and insulin, and both these hormones can make it easier for some cancers to grow. Gapstur says that’s one reason why it’s important to maintain a healthy weight throughout life.
That starts in childhood. “We know that kids who are heavy are more likely to become heavy adults. So, it’s important for parents to help their children learn good habits about healthy eating and staying active early in life.”
We are still trying to understand whether adults who are overweight or obese can reduce their chances of getting cancer if they lose weight, Gapstur says. “What research has shown is that losing weight lessens your chances of getting some other chronic diseases. And some of those diseases, such as diabetes, may increase your chance of getting some types of cancer.”
Certain foods are linked to a higher or lower risk for some types of cancer. Based on this evidence, the ACS recommends:
“We know that a person’s choices occur within the context of a larger environment,” Gapstur says. That’s why the ACS also recommends that communities and health care policies work to increase access to affordable, healthy foods, and restricting marketing of foods with low nutritional value.
Research shows that not being physically active increases your chance of getting some types of cancer. This includes colon and breast cancer and maybe several others. Here’s what the ACS recommends for adults and children:
The good news is that doing any kind activity beyond your usual ones can benefit your health, Gapstur adds.
Overall, Gapstur says, the key message is that prevention has the potential to substantially reduce the number of people diagnosed with and dying from cancer each year.
