Doctors are seeing a worrying trend: more young people under the age of 50 are being diagnosed with colorectal cancer, which includes cancers of the colon and rectum. This rise in cases has led scientists to search for reasons behind it.
A recent study published in the journal eBioMedicine has found something interesting. It shows that the bacteria found in the tumors of young patients are different from the bacteria found in the tumors of older patients. This difference might help explain why more young people are developing this kind of cancer.
The American Cancer Society has reported that each year, both the number of new cases and the number of deaths from colorectal cancer in young people are going up.
Experts believe that by 2030, the number of colon cancer cases in young people could double, and the number of rectal cancer cases could even quadruple. These predictions have made doctors and researchers very concerned.
Dr. Alok Khorana, an oncologist at the Cleveland Clinic, led the new study. His team used advanced technology to look at tissue samples from young patients with colorectal cancer. They compared these samples with those from older patients.
The study found that younger patients not only had more bacteria in their tumors but also had different types of bacteria. In particular, bacteria like Akkermansia and Bacteroides were more common in younger people’s tumors.
This discovery is important because it gives scientists new clues about what might be causing the rise in colorectal cancer among younger people. If doctors can better understand how certain bacteria are linked to cancer, they may be able to find new ways to prevent, detect, or treat it.
For example, in the future, there might be tests that can find these bacteria early, even before cancer develops. This would help catch the disease sooner when it is easier to treat. There might also be treatments designed to target these bacteria and stop them from helping cancer grow.
The first authors of the study, Dr. Shimoli Barot and Dr. Naseer Sangwan, say that these bacterial changes could be used to develop new tools to diagnose and treat colorectal cancer earlier and more effectively.
However, they also say that more research is needed. Scientists want to understand how lifestyle factors—like diet, use of certain medicines, and obesity—might change the bacteria in the gut and raise the risk of cancer in young people.
This research is a big step toward solving the mystery of why colorectal cancer is becoming more common among younger people. It gives hope that better ways to prevent and treat the disease are on the horizon.
Besides this study, other research shows there are things people can do to lower their risk of cancer. Regular exercise, for example, seems to help protect against many types of cancer. Getting enough vitamin D may lower the risk of dying from cancer.
Eating a diet rich in yogurt and fiber might even reduce the risk of lung cancer. Scientists are also developing new treatments that help the body’s own immune system fight cancer more effectively.
All these studies highlight how important it is to understand cancer better. They also show that making healthy lifestyle choices—like exercising, eating well, and protecting your gut health—might play a big role in keeping cancer away.
If you care about cancer, please read studies about supplement that may increase cancer risk, and can vitamin D help prevent or treat cancer?
