Colon cancer was once thought to be a disease that primarily affected older adults. But new data shows that this dangerous condition is increasingly being diagnosed in younger people, especially millennials. Medical experts are now sounding the alarm about this alarming new trend and urging the public to watch for key early symptoms.
A Troubling Trend: Colon Cancer Among Millennials
Doubling Risk in Those Born After 1990
A recent study published in the British Journal of Surgery (BJS) revealed a shocking statistic—individuals born in 1990 have twice the risk of developing colon cancer compared to those born in 1950. This rising tide of early-onset cases is concerning both physicians and public health experts.
Dr. Joseph Salhab, a Florida-based gastroenterologist, has highlighted the importance of early detection and has warned young adults to be aware of five critical warning signs that could indicate colon cancer. Identifying these symptoms early could make the difference between a treatable case and a life-threatening diagnosis.
Let’s dive into the signs and why they matter.
5 Early Warning Signs of Colon Cancer in Young Adults
1. Rectal Bleeding
Don’t ignore blood in your stool.
According to Dr. Salhab, rectal bleeding is one of the most serious red flags. Whether the blood appears dark red in your stool or bright red on toilet paper, it must not be brushed off. While sometimes related to hemorrhoids or minor conditions, repeated or persistent bleeding warrants immediate medical attention.
2. Persistent Abdominal Pain or Cramps
Stomach pain shouldn’t be dismissed.
If you’re dealing with repeated or unexplained abdominal pain, it might be more than an upset stomach. Pain that doesn’t respond to lifestyle changes or dietary improvements could be a sign of inflammation or obstruction—both potential warning signs of colon cancer.
Common sensations include:
-
Cramps
-
Sharp or dull pains in the lower belly
-
Ongoing bloating or discomfort
3. Constant Fatigue or Weakness
Feeling drained even after rest?
Persistent fatigue isn’t normal—especially if it interferes with your daily life. Many young people chalk this up to stress, work overload, or lack of sleep. But chronic tiredness or weakness, even after sufficient rest, could be linked to internal bleeding or anemia caused by colon cancer.
Dr. Salhab warns not to ignore this subtle yet serious symptom.
4. Changes in Bowel Habits
Your bathroom habits can tell you a lot.
If you notice changes in how frequently you poop, the texture of your stool, or experience constipation or diarrhea for several weeks, that’s something to monitor. A shift from your normal bowel pattern—including narrower stools—can signal something more serious.
If it lasts longer than a couple of weeks, speak to your doctor promptly.
5. Other Concerning Symptoms
Keep an eye out for:
-
Unexplained weight loss
-
Loss of appetite
-
Night sweats
-
Mild but persistent fevers
These may not seem significant when they occur alone. But when combined with the symptoms above, they can make a compelling case for early testing and diagnosis.
Why the Rise in Colon Cancer Among Young People?
Lifestyle, Diet, and Environmental Influences
Here’s what researchers believe is fueling the rise:
-
Sedentary lifestyles
-
Processed and low-fiber diets
-
Obesity
-
Smoking and alcohol use
-
Genetic predispositions
Dr. Salhab and researchers like Sara Char, lead author from the study, both emphasize the need for early screening, especially as early-onset cases continue to rise globally.
Are You at Risk?
While anyone can develop colon cancer, the risk is higher for:
-
Individuals with a family history
-
History of inflammatory bowel diseases
-
Poor dietary habits, low in fiber and high in red meat
-
People with obesity or low physical activity levels
If you have any of these risk factors, it’s essential to speak to your healthcare provider even if you’re under 40.
The Call for Awareness: Don’t Wait for Symptoms to Get Worse
Most young adults don’t believe they’re at risk for colon cancer, so they may ignore early signs. This leads to delays in diagnosis, and unfortunately, many cases are caught only in later stages. That’s why awareness is key—recognizing symptoms early can lead to prompt treatment and a better outcome.
If you or someone you know is experiencing any of the symptoms above, consult a doctor and consider getting screened earlier than standard guidelines suggest.
