From Constipation to Feeling ‘Full’ Too Soon: Top Doctor Warns Against 6 Colon Cancer Red Flags

Introduction

A senior oncologist has issued a strong warning about early signs of colon cancer, saying most patients ignore the symptoms until the disease reaches an advanced stage.
Colon cancer, also known as colorectal cancer, is rising among adults under 45 globally — something doctors are now calling “a hidden epidemic.”

The doctor pointed out that common digestive problems may actually be early warning signs if they persist for weeks.

6 Warning Signs You Should Never Ignore

1. Constipation that doesn’t go away

If your bowel movements remain irregular for weeks or you constantly feel the need to pass stool but nothing happens, it could indicate a blockage in the colon.

2. Feeling ‘full’ very quickly

When the stomach feels full after eating very little, it may be due to swelling or obstruction in the intestine.

3. Blood in the stool

Many people assume it is due to piles, but doctors warn that blood in stool should always be checked.

4. Sudden change in bowel habits

Frequent diarrhea, thin pencil-like stool, or alternating constipation and diarrhea can signal changes in the colon.

5. Unexplained weight loss

Losing weight without any diet or exercise changes is a major red flag and could indicate cancer activity.

6. Constant abdominal pain or discomfort

Long-term cramps, gas, or a feeling of pressure that doesn’t go away should be examined.

The doctor says these symptoms are often dismissed as “digestive issues,” which delays diagnosis.

Colon Cancer Is Rising in Younger Adults

Earlier, colon cancer was largely seen in older people.
Now, doctors say more cases are being found in those in their 20s, 30s, and early 40s.

Reasons behind this increase may include:

• Low-fiber diets
• Processed and junk food consumption
• Lack of exercise
• Smoking and alcohol use

The doctor added that awareness is the first step to prevention.

When Should You See a Doctor?

You should immediately seek medical attention if:

• Symptoms last longer than two weeks
• There is blood during bowel movements
• You notice a sudden change in appetite or energy levels

Doctors suggest getting tested if you have a family history of cancer or digestive diseases.

A simple screening test, colonoscopy, can help detect cancer early, when it is most treatable.

Conclusion

Digestive discomfort may look normal, but if symptoms remain consistent, it could be signaling something more serious.
Recognizing the early signs of colon cancer can save lives.

The doctor’s message is clear:

👉 “Do not ignore changes in your bowel habits. Early detection is the best protection.”
