A new study from the American Cancer Society found that about 40% of new cancer cases and nearly half of cancer deaths among adults in the U.S. are due to preventable factors. Key risk factors include smoking, excess body weight, alcohol use, lack of physical activity, poor diet, and infections like HPV.
These are things that people can practically change how they live every single day to reduce their risk of cancer”
Dr. Arif Kamal, Chief Patient Officer with the American Cancer Society
Leading Risks
Smoking is the top risk, responsible for nearly 1 in 5 cancer cases and almost a third of cancer deaths. Other factors include obesity, linked to 5-11% of new cases, and infections like HPV, which is nearly entirely preventable with a vaccine.
Obesity is emerging, in some ways, as just as potent of a risk for people as smoking is”
Dr. Marcus Plescia, Chief Medical Officer for the Association of State and Territorial Health Officials
Researchers studied 18 lifestyle factors across 30 cancer types, finding that in 2019, these factors led to over 700,000 new cancer cases and over 262,000 deaths. Some cancers, like lung and cervical cancer, are particularly linked to these risk factors.
Reducing Risk
Experts emphasize that people can reduce their cancer risk through everyday lifestyle changes, such as quitting smoking, maintaining a healthy weight, eating well, and staying active. Tobacco products are major risk factors for many cancers. You can maintain a healthy weight through a balanced diet rich in fruits, vegetables, and whole grains. It is also good to try and limit your intake of red and processed meats. Stay physically active with regular exercise. Limit alcohol consumption and avoid excessive sun exposure by using sunscreen and wearing protective clothing. Get vaccinated against infections like HPV and hepatitis B, which can lead to cancer. Regular screenings and check-ups can also help detect early signs of cancer, improving the chances of successful treatment. These changes can make a significant difference in preventing cancer and improving overall health.
