Colon cancer ranks among the most common cancers globally, yet it often slips under the radar due to its subtle symptoms. “It’s a cancer that can creep in quietly, and by the time it's diagnosed, it may already be at an advanced stage,” says Dr Sajjan Rajpurohit, Medical Oncology at BLK-Max Super Speciality Hospital. Early detection, he stresses, is the most powerful tool in improving survival rates.Early Symptoms People IgnoreColon cancer rarely announces its presence with dramatic symptoms. More often, it whispers — through changes in bowel habits, subtle abdominal discomfort, or unexplained weight loss.Some of the most commonly missed early signs include:Persistent changes in bowel movements: Chronic constipation or diarrhea often dismissed as dietary effects.Blood in stool: Bright red or dark blood should not be ignored.Unexplained weight loss: Especially when unintentional.Abdominal cramps or bloating: Misinterpreted as common digestive issues.“These symptoms are frequently brushed aside or self-diagnosed,” notes Dr Rajpurohit. “There’s a tendency to blame food, stress, or lifestyle rather than consider a deeper issue.”Don’t Ignore Blood in StoolAccording to Dr Rajpurohit, “Blood in the stool is one of the most common and concerning signs. While it might be due to hemorrhoids or fissures, it’s important not to assume. A proper evaluation is critical.”Ignoring such a red flag delays diagnosis and drastically reduces treatment success rates. A timely visit to a healthcare provider can change outcomes.The Bowel-Brain ConnectionPersistent changes in bowel habits, especially if they last more than a few days, must be taken seriously. Narrow or ribbon-shaped stools may indicate a tumor partially blocking the colon. “Changes in stool shape, frequency, or associated pain should raise suspicion,” Dr Rajpurohit explains.Social stigma and discomfort around discussing bowel habits further contribute to delay. “It’s high time we normalise conversations about gut health,” he adds.Exercise as Medicine: Post-Treatment InsightsA recent international study presented at the American Society of Clinical Oncology (ASCO) highlighted a groundbreaking revelation — regular exercise post-treatment for colon cancer patients significantly reduces recurrence and boosts survival.Dr Rajpurohit agrees: “This changes how we approach post-treatment care. Exercise isn’t just about fitness; it’s about survival. Oncologists must now prescribe movement as a form of medicine.”Lifestyle and Prevention Go Hand in HandColon cancer isn’t just a disease to treat — it’s one we can often prevent. The focus, says Dr Rajpurohit, should be on public education around:Diet: More fibre-rich fruits, vegetables, and whole grains; less processed food and red meat.Physical activity: “Even 30 minutes of daily walking helps.”Screenings: Especially vital for those over 45 or with a family history.“We must push for more awareness campaigns. Prevention is within reach, but people need the right information,” he stresses.The Way ForwardColon cancer is beatable — but only if people are aware of the risks and act early. As Dr Rajpurohit puts it, “Our job is not just to treat cancer but to educate, prevent, and empower. A healthy lifestyle, awareness, and regular screenings can save lives. The earlier we talk about it, the better we fight it.”
