When TikToker Radwah Oda revealed her colon cancer diagnosis, her goal wasn’t just to share her journey—it was to warn others not to ignore potential symptoms.

Her message resonated with thousands, highlighting how easy it is to overlook warning signs that could indicate a serious health issue.

“If you experience any of these symptoms, don’t panic, but see a doctor. Advocate for yourself,” she urged in her viral post.

Though colon cancer is often linked to older adults, it can develop at any age. One of its dangers is that it progresses silently, with symptoms often appearing only when the disease has advanced. Below are five key warning signs that experts, including Radwah, believe should never be ignored.

1. Changes in Stool Shape

Many people don’t pay close attention to their stool, but its shape can provide crucial health clues. If stools become consistently thin or pencil-like, it may indicate a blockage in the colon, often caused by a tumor. While occasional changes can be harmless, persistent narrowing over weeks should be discussed with a doctor.

2. Unexplained Changes in Bowel Habits

A sudden and lasting shift in bathroom routines can also signal trouble. Some individuals may experience persistent diarrhea, while others struggle with constipation or a constant urge to go but can’t. These irregularities occur when tumors obstruct normal colon function or irritate the intestinal lining. While dietary changes, stress, or infections can temporarily disrupt digestion, ongoing bowel changes lasting more than two weeks should be checked by a healthcare provider.

3. Persistent Fatigue

Feeling drained after a busy day is normal, but exhaustion that lingers despite rest may point to an underlying issue, including colon cancer. The body expends significant energy fighting serious illnesses, leading to chronic fatigue. If tiredness persists without explanation, particularly when paired with digestive issues or unexplained weight loss, it’s important to seek medical evaluation.

4. Unexplained Abdominal Pain

Radwah shared that one of her earliest symptoms was pain on the lower right side of her body, which she initially dismissed as discomfort from a tight bra. In many cases, abdominal pain—especially in the lower left side, where the sigmoid colon is located—can signal a blockage caused by a tumor. Persistent or recurring pain in the same area, particularly if unresponsive to common treatments, should not be ignored.

5. Chronic Bloating

Occasional bloating is common, but ongoing discomfort and swelling without an obvious cause may indicate a more serious issue. Colon cancer can cause obstructions in the intestines, leading to trapped gas and a persistent feeling of fullness. Women, in particular, often normalize bloating, but when it becomes frequent or occurs alongside other symptoms, it’s crucial to consult a doctor.

Stay Vigilant About Your Health

While these symptoms don’t always mean cancer, they should never be overlooked. Early detection significantly improves outcomes, making it essential to listen to your body and seek medical advice if symptoms persist. Radwah’s story serves as an important reminder—advocating for your health can make all the difference.
