Why Colorectal Cancer is Rising Among Young People: What You Need to Know (2026)

Here’s a shocking fact: colorectal cancer has now surpassed other cancers as the leading cause of cancer-related deaths in people under 50. But why is this happening, and what can we do about it? Researchers are still piecing together the puzzle, but current evidence points to lifestyle and environmental factors as key culprits. And here’s where it gets even more intriguing: the colon is uniquely vulnerable because, as one expert puts it, ‘everything you put into your body, your colon will see.’ Yet, despite these clues, the full picture remains frustratingly unclear.

Anjee Davis, CEO of Fight Colorectal Cancer, highlights a critical issue: ‘If cancer were more of a national priority, answers wouldn’t be so elusive.’ She shares heart-wrenching stories of young people—as young as 11, 17, and 20—being diagnosed with this disease. ‘It really breaks my heart,’ she says. The data backs her up: three out of four patients under 50 are diagnosed only after the cancer has reached an advanced stage. And this is the part most people miss: early detection is a game-changer. According to the CDC, 89% of people diagnosed at the earliest stage survive at least five years, compared to just 16% at the most advanced stage.

A 2024 study revealed a troubling delay: it takes an average of four to six months for patients to receive a diagnosis after symptoms appear. The most common warning signs? Abdominal pain, blood in the stool, and persistent changes in bowel habits—like ongoing diarrhea or constipation. Other red flags include unexplained weight loss, persistent fatigue, and the feeling that a bowel movement isn’t complete. But here’s where it gets controversial: Are we doing enough to educate people about these symptoms, or are we letting stigma and discomfort get in the way?**

High-risk groups face even greater challenges. While most people are advised to start screenings at 45, family history, genetic conditions, and certain symptoms can push that timeline earlier. Shockingly, fewer than 30% of 45- to 49-year-olds are up to date on their screenings, compared to over 70% of older adults. Two groups are disproportionately affected: Native Americans and Alaska Natives, who have the highest global incidence rates, and Black men, who face a 40% higher risk of dying from colon cancer than white men. Why aren’t these disparities being addressed more aggressively?

Family history plays a critical role, but it’s not always straightforward. If a parent or sibling had colon cancer, your risk increases, and screenings should start 10 years before their diagnosis age. For example, if your mother was diagnosed at 45, you should start at 35. But here’s the twist: even a family history of stomach, pancreatic, or breast cancer can elevate your risk. ‘Certain cancers run together, showing up differently in different people,’ explains expert Kamal. His advice? Compile your family’s medical history and bring it to your doctor. ‘Write it all down. Go talk to your doctor.’

Stigma is another silent killer. Many people avoid screenings because they’re uncomfortable discussing bowel habits. Lynn Durham, a cancer survivor and CEO of Georgia CORE, puts it bluntly: ‘People don’t want to talk about their poop. But if your stool changes dramatically, something’s wrong—see your doctor immediately.’ Anjee Davis advocates for normalizing these conversations, starting with families. ‘We talk about babies’ poop all the time. Why stop as we age?’ She suggests asking straightforward questions: ‘How regular are you? Have you noticed changes? Have you talked to your doctor about rectal bleeding or constipation?’ But is society ready to embrace this level of openness?

Even medical providers aren’t immune to bias. Many doctors still associate cancer with older adults, leading them to dismiss symptoms in younger patients. ‘A 35-year-old with a breast lump gets attention, but belly pain and blood in the stool? Often brushed off as minor issues,’ Kamal notes. This oversight contributes to the high mortality rate. Davis urges patients not to settle for dismissive explanations: ‘If a doctor tells you to just eat fiber, find another healthcare provider. Young patients need to be heard.’ Are we failing younger patients by not taking their symptoms seriously?

While research evolves, lifestyle changes can make a difference. Limiting red and processed meats while increasing vegetables, fruits, and whole grains may lower your risk. ‘Small changes today can impact your risk 10 years from now,’ Kamal says. For advocates like Durham and Davis, the urgency is personal. Durham has survived cancer three times, and Davis has fought for patients diagnosed too late. ‘This is a preventable cancer,’ Davis says. ‘We have the power to figure this out. I know we do.’ But the question remains: Are we doing enough? What do you think? Is colorectal cancer getting the attention it deserves, or are we falling short? Share your thoughts in the comments.
