When TikToker Radwah Oda revealed her colon cancer diagnosis, her goal was to help others recognize symptoms she had once ignored. Her message resonated widely, highlighting how easily early warning signs can be overlooked.

“If you have any of these symptoms, please don’t panic — but do see a doctor. Advocate for yourself,” she urged in her viral video.

While colon cancer is often linked to older adults, it can develop at any age. The danger lies in its ability to progress quietly until it’s more advanced. Here are five signs you shouldn’t ignore, based on Radwah’s experience and medical advice.

1. Changes in Stool Shape

Most people rarely notice the shape of their stool, but consistent changes can be a red flag. Stools that are persistently thin or “pencil-like” may indicate a narrowing in the colon caused by a tumor or obstruction. Occasional variations are normal, but if the change persists for more than a couple of weeks, consult your doctor.

2. Unexplained Changes in Bathroom Habits

A sudden shift in your bowel routine — such as frequent diarrhea, constant urges without relief, or difficulty passing stool — may signal a problem. Tumors can block or irritate the intestines, disrupting normal function. If this continues beyond two weeks, especially with other symptoms, seek medical attention.

3. Persistent Fatigue

Feeling tired is normal after a busy day, but exhaustion that lingers despite adequate rest may be a warning sign. Chronic fatigue in colon cancer can result from the body’s ongoing effort to fight illness, and it may come with dizziness or shortness of breath. Don’t dismiss ongoing fatigue as just aging or stress — get it checked.

4. Abdominal Pain

Radwah experienced discomfort on the lower right side of her body for months, blaming it on tight clothing. Persistent pain — especially in the same spot, such as the lower left side where the sigmoid colon is located — can be a sign of a blockage or tumor. If the pain doesn’t improve, see a doctor.

5. Persistent Bloating

Occasional bloating is common, but ongoing bloating with discomfort or a sense of fullness after small meals may indicate a blockage. If it occurs regularly without clear cause, and especially if it’s paired with changes in bowel habits or abdominal pain, it’s worth investigating.

Early Detection Saves Lives

Colon cancer has a high survival rate when detected early. These symptoms don’t always mean cancer, as other conditions can cause them, but persistent changes should never be ignored. Awareness, regular screenings (starting at age 45 for most people), and timely medical advice are key.
