Colorectal cancer, which includes cancers of the colon and rectum, is one of the most common cancers in the world. It affects the large intestine, an important part of the digestive system that absorbs water and processes waste before it leaves the body.
This disease often develops slowly over many years, starting as small growths called polyps that may eventually turn into cancer.
When found early, colorectal cancer can often be treated successfully, but if it is discovered late, it can become life‑threatening. In recent years, doctors have become especially concerned because cases are rising among adults under the age of 50.
Just before National Colorectal Cancer Awareness Month in March, a new survey highlighted how little many people know about one major risk factor: processed meat.
The poll was conducted by the Physicians Committee for Responsible Medicine together with Morning Consult and included 2,202 adults across the United States between February 9 and 11, 2026. The findings showed that nearly half of Americans did not realize that eating processed meat increases the risk of colorectal cancer.
Processed meats include foods such as bacon, sausages, hot dogs, ham, and deli meats. These products are preserved by smoking, curing, or adding chemicals to improve flavor and shelf life.
Scientists have long warned that these methods can create harmful compounds that may damage cells in the digestive system over time. In fact, the World Health Organization classified processed meat as a known cause of cancer several years ago, based on strong scientific evidence.
After survey participants were told about the link between processed meat and cancer risk, two out of three said they would support warning labels on these products. This suggests that people want clear information to help them make healthier choices.
Dr. Joseph Barrocas, an internal medicine specialist from North Carolina, noted that it is worrying that so many people remain unaware of the connection, especially now that colorectal cancer is a leading cause of cancer deaths in younger adults.
The poll also found that only about one‑third of adults said a health care professional had ever talked to them about the relationship between diet and colorectal cancer.
This gap in communication may prevent people from understanding how daily food choices affect long‑term health. Experts say doctors and nurses should discuss both screening tests and lifestyle changes that can reduce risk.
Research shows that diet plays a powerful role in protecting the colon. People who follow a plant‑based eating pattern rich in fruits, vegetables, whole grains, and beans tend to have a lower risk of colorectal cancer.
One study found that those eating mostly plant foods had about a 22 percent lower risk compared with people who regularly ate meat. Plant foods contain natural substances that help fight inflammation and protect cells from damage.
Fiber is another key factor. Fiber is the part of plant foods that the body cannot fully digest. It helps move waste through the intestines more quickly and supports healthy bacteria in the gut.
Studies show that people who eat the most fiber have a much lower risk of developing colon polyps, which can be early warning signs of cancer. Nutrition experts estimate that for every 10 grams of fiber added to the daily diet, the risk of colorectal cancer may drop by about 10 percent.
Other lifestyle habits also matter. Maintaining a healthy body weight, limiting alcohol, staying physically active, and avoiding smoking can all reduce the chances of developing colorectal cancer. Regular screening tests, such as colonoscopies, are especially important because they can find and remove polyps before they become cancerous.
This survey highlights a serious public health challenge. While scientific knowledge about diet and cancer has grown, public awareness has not kept pace. The findings suggest that better education, clearer food labeling, and more conversations between patients and health professionals could help prevent thousands of cases each year.
However, surveys measure opinions and awareness rather than direct health outcomes, so further research is needed to understand how education campaigns might change behavior and reduce cancer rates.
In summary, the study shows that many people still lack important information about how processed meat affects cancer risk, but it also reveals a strong willingness to learn.
Providing clear guidance about healthy eating, encouraging plant‑rich diets, and promoting regular screening could play a major role in reducing colorectal cancer in the future. Greater awareness may ultimately save lives by helping people make informed choices long before disease develops.
If you care about cancer, please read studies that a low-carb diet could increase overall cancer risk, and vitamin D supplements could strongly reduce cancer death.
