Doctors Point to Nutrition as Key to Improving Worrisome Cancer Statistics Outlined in New American Cancer Society Report
WASHINGTON, D.C.—In its annual cancer statistics report, the American Cancer Society (ACS) predicted over 2 million new cancer cases and over 600,000 cancer deaths in the United States in 2024. The ACS cites decreased smoking rates, earlier detection, and improved treatments as the primary reasons for decreased death rates from cancer in recent decades. Missing from the report, doctors say, is the fundamental recommendation to shift from the traditional American diet high in meat and dairy products to one focused on whole, plant-based foods.
Of particular concern in the report is the rise in colorectal cancer rates in young people. In the late 1990s, colorectal cancer was the fourth leading cause of cancer deaths in men and women under 50 years. It has risen to the leading cause of cancer death in men aged 20-49 years, and the third leading cause in women aged 20-39 years, after breast and cervical cancers.
“Processed meat has been categorized as a Group 1 carcinogen by the World Health Organization since 2015, and yet bacon and hot dogs are still served in many hospitals and schools. We need to do better,” says Dr. Roxanne Becker, MBChB, DipIBLM, medical editor and educator with the health and nutrition advocacy nonprofit the Physicians Committee for Responsible Medicine, which has more than 17,000 doctor members.
She adds, “Our research shows that the best way to improve the quality of your health is to improve the quality of the foods you eat, and that means avoiding animal products and eating a diet rich in fruits, vegetables, grains, and beans.”
Obesity, a key risk factor for many cancers, increases the risk of gastrointestinal cancers, including colorectal and non-colorectal GI cancer. Research shows that people who are overweight or obese in early and middle adulthood, or who either fail to lose weight or gain more weight, have an increased risk of the disease.
Red and processed meat consumption can increase the risk of colorectal, pancreatic, and prostate cancers, among others. Grilling and smoking meat make it more dangerous to human health. A plant-based diet, on the other hand, is one of the most effective ways to reduce overweight and obesity and lower the risk of colon cancer.
According to a study published in BMC Medicine, men who ate the most plant-based foods had a 22% reduced risk of colon cancer, compared with those who ate the least. “Eating a plant-based diet increases consumption of fiber and antioxidants associated with cancer prevention, while simultaneously avoiding the compounds in animal products linked to cancer risk,” Dr. Becker explains. “It has long been known that people who avoid meat are at reduced risk.”
The Adventist Health Study-2 has also shown the benefit of a plant-based diet for lowering the risk of cancer and death from any cause. Researchers compared all-cause mortality and cancer incidence rates in Seventh-day Adventist participants, who often follow a plant-based diet, with the general U.S. population documented in census data. Early death and cancer incidence rates were lower among Black study participants by 36% and 22%, respectively, compared with Black people in the census data. Studies have also shown the benefits of consuming more plants in lowering the risk of breast, prostate, and colorectal cancers.
Statistics like this citing a means of reducing cancer rates among Black Americans is especially important; the American Cancer Society also reported that Black men had the highest overall cancer rates and that Black women's death rate from breast cancer was 41% higher and from uterine cancer was double the rate among white women.
According to the U.S. Department of Health and Human Services Office of Minority Health, African American adults have the highest mortality rate of any racial and ethnic group for all cancers combined and for most major cancers.
Research shows that a whole food, plant-based diet leads to a healthier weight, which decreases the likelihood of developing obesity, a risk factor for many illnesses and ailments, including cancer. The Physicians Committee offers a wealth of free education and nutrition resources, including the Vegan Kickstart.
