Colon Cancer Is A Growing Risk For Older Millennials

Colon cancer has long been seen as an “older person’s disease.” But that perception is shifting fast. Rates of colorectal cancer are rising sharply among people under 50, and for Black men and women, the risks are even more pronounced. This isn’t just about statistics; it’s about real lives and what we can do to protect them.

The Growing Threat

Colon cancer is no longer just a concern for older adults. Over the past two decades, cases among people under 50 have risen steadily, climbing by around 1 to 2 percent annually. According to the University of Washington School of Medicine, colorectal cancer is expected to become the leading cause of cancer-related deaths for those under 50 by 2030.

What’s even more troubling is how often younger patients are blindsided. Many don’t have a family history of the disease or other traditional risk factors, which leaves symptoms like abdominal pain, unexplained weight loss, or changes in bowel habits dismissed or overlooked until it’s too late.

For younger adults, this delay often means the cancer is diagnosed at a more advanced stage, complicating treatment options and outcomes.

What’s Behind the Numbers?

While the exact reasons for the rise in early-onset colorectal cancer aren’t fully understood, researchers point to several likely contributors:

Dietary Shifts

The modern Western diet, rich in processed foods and low in fiber, has been linked to an increased risk of colon cancer. Fiber is key to a healthy gut, yet most Americans fall far short of the recommended 25 to 34 grams daily.

Studies suggest that fiber can lower colon cancer risk by up to 15 percent, but diets heavy in fast food and processed snacks do the opposite.

Inactivity and Obesity

The connection between obesity and colorectal cancer risk is well-established, with obesity increasing the likelihood by approximately 30 percent, according to the CDC. Lack of exercise only makes matters worse. Regular physical activity helps reduce inflammation, improves gut health, and directly lowers cancer risk, but sedentary lifestyles are far too common.

Gut Microbiome Disruption

According to the National Library of Medicine, poor diets and long-term antibiotic use can throw gut bacteria balance off track, potentially accelerating cancer development. The gut microbiome is vital for digestion and immunity, but these disruptions may pave the way for disease.

Genetics and Environmental Factors

While inherited conditions like Lynch syndrome play a role for some, the majority of younger colon cancer patients don’t have a family history, suggesting environmental exposures or unidentified triggers may contribute.

Why Colon Cancer Hits Our Community Harder

For Black Americans, the picture is even more alarming. We are 20 percent more likely to develop colorectal cancer and 40 percent more likely to die from it than other racial groups, according to the American Cancer Society. These disparities stem from more than just biology; they’re shaped by systemic inequities that create barriers to care and prevention. Some obstacles that challenge our community include:

• Living in Food Deserts: Living in areas without access to fresh, affordable food makes it much harder to maintain a fiber-rich, cancer-fighting diet. Processed and high-fat foods dominate in these environments, increasing risk factors like obesity.
• Issues Access Healthcare and Screenings: Our community faces limited access to healthcare and insurance, leading to delayed colorectal cancer screenings. Only 65 percent of Black Americans participate in recommended screenings, compared to higher rates in other populations.
• Receiving Diagnosis at Later Stages: Black patients are more likely to be diagnosed at advanced stages of the disease. Nearly 26 percent of early-onset cases in Black Americans are metastatic at diagnosis, compared to 22 percent among White Americans, according to the Colon Cancer Foundation.

What You Can Do

While colon cancer may feel intimidating, there’s a lot you can do to protect yourself and those you love. Start by paying attention to your body. If you notice changes in bowel habits, unexplained weight loss, blood in the stool, or persistent fatigue, don’t brush it off. Push for answers, and if your concerns aren’t taken seriously, get a second opinion. Early detection saves lives.

Screenings are your best defense. The American Cancer Society now recommends starting screenings at age 45 for those at average risk.

But if you have a family history or other factors, consider starting earlier. Screenings can detect early-stage cancers and even remove precancerous polyps before they develop into something more dangerous.

Small lifestyle changes can also make a big difference. Here are some things to consider:

•  Include fiber-rich foods like fruits, vegetables, legumes, and whole grains in your diet.
•  Aim for 150 minutes of moderate weekly exercise to lower inflammation and improve overall health.
• Cut down on processed and red meats while maintaining a healthy weight.
• Most importantly, normalize conversations about health within your family. Sharing medical histories and discussing symptoms can empower everyone to seek care sooner.

Rewriting the Narrative

Colon cancer doesn’t fit its old stereotypes anymore. It’s showing up earlier, hitting harder, and disproportionately affecting our community. But awareness and action can change the story. With stronger advocacy for screening, lifestyle shifts, and open conversations, we can face this challenge together. Let’s protect ourselves, our families, and our future by putting health at the forefront, because this is one fight we can take on and win.
