We all know our digestive system plays a big role in how we feel day-to-day. But what if some of those “minor” stomach issues are actually red flags? Colon cancer is one of the most common—and deadliest—cancers, and it often sneaks in quietly. The tricky part? Its early symptoms can easily be brushed off as routine digestive annoyances.

Let’s talk about five subtle but serious warning signs of colon cancer that could save your life if you spot them early. We’re not here to scare you—but awareness can make all the difference

Constipation or Diarrhea That Sticks Around

Everyone has the occasional off day when it comes to the bathroom. Maybe you had too much cheese or a questionable burrito. But if constipation or diarrhea becomes your new normal, it’s time to pay closer attention.

A persistent change in bowel habits—especially if it lasts more than a few days—can be one of the earliest signs of colon cancer. Tumors can mess with the flow of waste through your colon, causing blockages (hello, constipation) or irritation (leading to diarrhea). If your digestive rhythm feels out of sync and nothing seems to fix it, it’s worth getting checked.

Abdominal Swelling or Bloating That Won’t Budge

We all get bloated now and then—carbonated drinks, salty snacks, or that giant pasta bowl will do it. But if your stomach seems to be in a permanent state of puffiness or feels tight and uncomfortable often, that’s not just food-related bloat.

Colon cancer can cause a backup in your intestines, trapping gas and fluids that lead to swelling. This kind of bloating doesn’t just make your jeans snug—it can signal that something’s blocking the normal flow in your digestive tract. If adjusting your diet doesn’t help, it’s time to speak up.

Bathroom Trips Are Suddenly More Frequent

Do you feel like you’re always looking for the nearest bathroom? A sudden and unexplained increase in how often you need to go—especially when it’s paired with urgency or thinner stools—can be a red flag.

When a tumor begins to press on or disrupt the colon’s function, it can make you feel like you constantly need to go, even if little comes out. This isn’t just annoying; it’s your body telling you something is off. Don’t ignore that growing urge.

Pain in the Lower Left Side of the Abdomen

Here’s a symptom that’s easy to misread. You might think that cramp on your lower left side is due to gas, menstrual cramps, or even how you slept. But persistent or increasing pain in that area can be linked to a tumor causing a blockage in the colon.

TikToker Radwah Oda shared her story about experiencing pain on the lower right side of her torso. She assumed it was from a tight bra and ignored it for months. Turns out, it was much more serious. Any consistent abdominal pain, especially if it’s new for you, should be taken seriously.

Unrelenting Fatigue You Can’t Shake

We all get tired. But when rest doesn’t fix it—and the tiredness keeps dragging on—it could be a sign your body is fighting something bigger.

Colon cancer can cause hidden bleeding inside your digestive tract, slowly draining your body’s iron and making you anemic. The result? You feel wiped out all the time, maybe dizzy or short of breath, and no amount of sleep seems to help. If you’re constantly running on empty without a clear reason, it’s time to dig deeper.

Think colon cancer only hits after age 50? Think again.

More young adults are being diagnosed with colon cancer than ever before. Stories like Radwah Oda’s are powerful reminders that age isn’t a shield. Her viral TikTok opened a conversation many people weren’t ready for—she was young, active, and looked healthy on the outside.

But she noticed her body was sending signals. And luckily, she listened—just in time.

Listen to Your Gut—Literally

Your gut is smarter than you think. When it’s off, it tries to tell you. And these symptoms—though easy to explain away—can be whispers from your body that something deeper is going on.

Colon cancer caught early is highly treatable. Left unchecked, it can become deadly. So if anything we talked about sounds familiar, don’t wait. Make the call. Get checked. Advocate for yourself.

Trust your gut. It’s looking out for you more than you realize.

Conclusion

Colon cancer often begins in silence—but it doesn’t have to stay that way. By learning to recognize early warning signs like changes in bowel habits, persistent bloating, sudden fatigue, or unexplained pain, you’re giving yourself a powerful advantage. These symptoms aren’t always cause for alarm, but they are cause for attention. Don’t brush them off. Don’t second-guess your instincts. When it comes to your health, it’s always better to ask questions early than face regrets later. Stay informed, stay alert, and most importantly—stay proactive.
