Colon cancer rising among youngsters: Top US doc alerts about 5 warning signs

Colon cancer, which was common in older adults, is, however, increasingly being diagnosed in younger people. Though age remains a risk factor for this cancer, recent studies are pointing to a troubling trend - millennials are facing rising rates of this deadly disease.

Colon cancer is a type of cancer that develops in the colon, which is the longest part of the large intestine. It's also known as colorectal cancer, as it can also occur in the rectum (the last part of the large intestine).

A recent study published in BJS found that compared to people born in 1950, those born in 1990 have twice the risk of developing colon cancer. Dr. Joseph Salhab, a Florida-based gastroenterologist, has spoken about the alarming rise in cases of colon cancer among young adults. The doctor has revealed five critical warning signs that should not be ignored. Early detection is key to successful treatment. Let's take a look at the warning signs and learn more.

Rectal bleeding

Dr. Salhab said that rectal bleeding is one of the most alarming signs of colon cancer. If you notice blood in the stool or on toilet paper, it should not be dismissed. This can look either dark or bright red. It could be a warning sign of colon cancer. While it may be caused by benign conditions like hemorrhoids, persistent or recurrent bleeding certainly requires immediate medical attention.


Unexplained abdominal pain

Belly pain should not be easily dismissed. If you have belly pain with no known cause, that doesn’t go away or hurts a lot, you should get it checked. Persistent abdominal discomfort that lingers despite changes in diet or lifestyle is a red flag. This pain may feel like cramping or bloating; however, it could be a subtle but critical indicator of colon cancer. If the discomfort lasts longer, talk to a healthcare provider.


Weakness or fatigue
Feeling tired all the time is not a good sign. Fatigue or weakness, even after proper rest could signal an underlying issue. People tend to dismiss this symptom, however, Dr. Salhab has waned that it could be a crucial sign. Young adults, who often lead busy lives, may attribute this to stress or lack of sleep. This could delay diagnosis. It is important to not ignore chronic fatigue.

Changes in bowel habits

How you poop matters. Changes in bowel habits, especially one that lasts more than a few weeks should raise concern. These changes could be either increased constipation, diarrhea, or even how often you poop. If these changes persist, you should talk to your doctor.


Other symptoms
Dr. Salhab also listed some other early signs of colon cancer. These include unexplained weight loss, loss of appetite, night sweats, or recurring low-grade fevers. Though these symptoms may be due to other health issues, when combined, they could point to colon cancer. So it is important to get it checked.


“The incidence of GI cancers in adults younger than age 50 is rising globally. Ongoing research efforts investigating the biology of early-onset GI cancers are critical to developing more effective screening, prevention, and treatment strategies,” lead author Sara Char, of the above-mentioned research, said. Lifestyle factors such as poor diet, sedentary behavior, and obesity, along with genetic predispositions, may also contribute to the risk of colon cancer.

This shift in colon cancer demographics has sparked concern among health experts worldwide. While routine screening for colon cancer typically begins at age 40's, many young adults remain undiagnosed until the disease has progressed to later stages. Experts are now advocating for greater awareness and earlier discussions with doctors, especially for those with a family history or persistent symptoms. If you notice any of the above signs, it is important to consult a doctor right away.
