10 Colon Cancer Warning Signs Young Adults Should Never Ignore

Colorectal cancer has emerged as one of the leading causes of cancer-related deaths among individuals under 50. While routine screenings often start at age 45, younger adults are not immune to the disease. Early detection is key, and recognizing the warning signs can make a significant difference in outcomes.

The American College of Surgeons (ACS) has developed educational resources to help younger adults identify potential symptoms and seek timely medical advice. Here are 10 symptoms, risk factors, and important steps that should not be overlooked.

10. Persistent Changes in Bowel Habits

Changes in bowel habits, such as constipation, diarrhea, or unusually narrow stools, can signal an underlying issue.

If these changes persist or are accompanied by a feeling of incomplete evacuation, it’s important to consult a healthcare provider.

9. Recurring Blood in the Stool

Blood in the stool is a significant warning sign that should not be overlooked.

Even a small amount of recurring blood warrants medical evaluation, as it could be an indicator of colorectal cancer.

8. Changes in Stool Color or Appearance

Alterations in stool color, such as bright red or dark, tarry stools, can indicate gastrointestinal bleeding.

These changes should be assessed by a healthcare professional, especially if they are persistent or recurrent.

7. Unexplained Weight Loss

Sudden, unexplained weight loss can be a sign of various health issues, including colorectal cancer.

It’s important to discuss significant or continuing unexplained weight loss with your doctor to identify the cause.

6. Persistent Tiredness or Weakness

Feeling constantly tired or weak, without a clear reason, can indicate an underlying health problem.

If fatigue is persistent and unexplained, it’s advisable to seek medical advice to determine the cause.

5. Reduced Appetite

A noticeable decrease in appetite can be a symptom of colorectal cancer or other health conditions.

Discussing changes in appetite with a healthcare provider can help identify potential underlying issues.

4. Nausea or Vomiting

If these symptoms are ongoing and unexplained, they should be evaluated by a medical professional.

3. Family History and Screening

A family history of colorectal cancer increases the risk and may necessitate earlier screening.

Discuss your family history with your doctor to determine the appropriate age to begin screening.

2. Inflammatory Bowel Conditions

Inflammatory bowel diseases (IBD), like Crohn’s disease or ulcerative colitis, can increase colorectal cancer risk.

Individuals with IBD should have regular discussions with their healthcare provider about when to begin colorectal cancer surveillance and how often it is needed.
