A TikToker shared her story.

TikToker @radwah.oda, Radwah Oda, recently went viral after bravely revealing her colon cancer diagnosis in a video aimed at raising awareness. She opened up about the subtle symptoms she initially dismissed, urging viewers to trust their instincts. “If you have any of these symptoms, please don’t panic — but do see a doctor. Advocate for yourself,” she advised.

While colon cancer is typically associated with older adults, it can affect people at any age — often without clear signs until it’s more advanced. That’s why recognizing early symptoms is key to improving outcomes.

Constipation or diarrhea

Constipation or diarrhea can be warning signs of colon cancer, especially if they last for more than a few days or occur frequently. These changes in bowel habits may happen because a tumor is affecting the normal function of the colon, causing blockages or irritation. If you notice persistent constipation or diarrhea without an obvious cause, it’s important to see a doctor for evaluation.

Stomach swelling

Ongoing abdominal swelling isn’t just a simple digestive nuisance—it might indicate a more serious health problem. For instance, colon cancer can create blockages in the intestines, causing gas to accumulate, leading to discomfort and a swollen belly.

Many people tend to ignore bloating as a minor issue, but if it happens often, becomes painful, or doesn’t get better with changes in diet, it’s important to see a doctor. Sometimes, bloating is caused by a tumor interfering with normal digestion, making early diagnosis essential.

Increased bowel frequency

Frequent trips to the bathroom aren’t always a cause for concern, but a sudden increase—especially when paired with changes in stool consistency or urgency—could point to an underlying issue.

In some cases, colon cancer may cause diarrhea, while in others, it can create the constant urge to go without much relief. These disruptions happen when a tumor interferes with normal bowel function. If you experience ongoing changes in your bathroom habits without a clear reason, it’s important to see a doctor.

Pain in the lower left side of the belly

Radwah Oda revealed that one of the initial symptoms she overlooked was pain on the lower right side of her torso, just below her breast. She assumed it was caused by a tight bra and ignored it for months, not realizing it could signal a more serious issue.

A tumor in the colon can create a blockage, preventing stool from passing and causing severe pain, often felt on the lower left side of the abdomen. If you notice persistent pain or changes in your bowel movements, it’s crucial to consult a doctor rather than dismiss these warning signs.

Never-ending tiredness

Feeling wiped out all the time—even after a full night’s sleep—might be more than just everyday tiredness. When exhaustion doesn’t go away with rest and comes with symptoms like dizziness or shortness of breath, it could point to something deeper. If you’re constantly low on energy without an obvious reason, it’s worth checking for possible health issues, including those linked to the colon.

Seemingly harmless skin issues can actually signal serious health problems.
