Colon cancer, also called colorectal cancer, has become one of the most serious health threats for younger adults in recent years. Doctors have noticed a worrying trend: more people under the age of 50 are being diagnosed with the disease than in the past.
In fact, colon cancer has now become the leading cause of cancer-related deaths for adults younger than 50 in the United States. This change has alarmed doctors and public health experts because colon cancer is actually one of the most preventable types of cancer if it is found early.
Colon cancer usually develops slowly over many years. It often begins with small growths called polyps that form on the inner wall of the colon or rectum. These polyps are not cancer at first, but some of them can gradually turn into cancer if they are not removed.
The good news is that screening tests can detect these polyps before they become dangerous. Doctors can remove them during the screening process, which stops cancer from developing later.
Despite this powerful prevention method, many people are not getting screened. A new nationwide survey commissioned by the Colorectal Cancer Alliance has revealed one major reason why colon cancer deaths may be increasing.
Millions of Americans simply do not know that screening is easy to access, and many do not realize that some tests can even be done at home.
The survey found that about half of Americans do not know that colon cancer screening can be done at home using simple stool-based tests.
These tests allow people to collect a small sample of stool privately in their own home and send it to a laboratory for analysis. The lab checks the sample for tiny amounts of blood or certain DNA changes that may suggest early signs of cancer.
The survey also showed that many people are unaware of the different types of screening available. About 37 percent of respondents said they did not know about all the ways doctors can check for colon cancer.
Several screening options exist today, including colonoscopy, stool tests, blood tests, CT colonography, and flexible sigmoidoscopy. Each method has different advantages, but all are designed to detect cancer early or prevent it entirely.
More than nine out of ten people who took part in the survey said they would be more likely to get screened if they knew screening could actually prevent colon cancer. This finding suggests that a lack of information is a major barrier to prevention.
Dr. Richard Wender, a medical adviser to the Colorectal Cancer Alliance and a professor of family medicine and community health at the University of Pennsylvania, explained that colorectal cancer is often highly treatable when discovered early.
According to him, increasing public awareness and encouraging conversations between doctors and patients could save many lives.
The survey also highlighted another serious problem. Younger adults often feel that their symptoms are not taken seriously by healthcare providers.
About one third of survey participants said a doctor had dismissed their digestive symptoms at some point. Among people younger than 45—the age when screening is usually recommended to begin—this number rose to 45 percent.
This issue can be dangerous because early-stage colon cancer often produces no symptoms at all. When symptoms do appear, they may include rectal bleeding, unexplained weight loss, or lasting changes in bowel habits. These warning signs should always be taken seriously, regardless of a person’s age.
The survey also identified several common reasons why people avoid screening. Nearly half of the participants said cost and fear were the biggest barriers. Some people worry about discomfort during medical procedures, while others are concerned about medical expenses.
Even among people who know about at-home tests, confusion remains. About 59 percent of participants did not realize that if an at-home stool test shows a positive result, a colonoscopy is usually required to confirm the diagnosis and examine the colon more closely.
Michael Sapienza, the CEO of the Colorectal Cancer Alliance, said the rising number of young people dying from colon cancer is unacceptable. He believes that improving public education about screening and increasing research funding are both necessary steps to address the growing problem.
Current medical guidelines recommend that adults with an average risk of colon cancer begin regular screening at age 45. However, people with higher risk factors may need to start earlier. These risk factors include a family history of colon cancer, inflammatory bowel diseases such as Crohn’s disease, and certain metabolic conditions such as type 2 diabetes.
The nationwide online survey was conducted by Wakefield Research and included responses from 1,000 adults in the United States during November and December. The results highlight a major gap between available medical technology and public awareness.
Overall, the findings suggest that colon cancer prevention may depend less on scientific breakthroughs and more on improving public understanding. The tools needed to detect and prevent the disease already exist, but many people simply do not know about them or do not use them.
From a public health perspective, this survey provides an important lesson. When lifesaving medical tools are underused because of lack of knowledge, education becomes just as important as medical treatment. Increasing awareness about simple screening methods, especially home tests, could help detect cancer earlier and prevent many cases entirely.
At the same time, the results show that healthcare systems must take younger patients’ symptoms seriously and avoid assuming that colon cancer only affects older adults. As the number of cases among younger people continues to rise, earlier conversations and better access to screening could play a key role in reversing this trend.
