Colorectal cancer early signs: What doctors say young adults should stop ignoring

A recent nationwide survey on gut health has revealed a concerning trend in Delhi: young and working-age adults are increasingly ignoring early warning signs of colorectal cancer. The Colorectal Cancer Awareness Survey, conducted across 14 Indian cities with over 10,000 participants, showed that awareness in the capital remains worryingly low despite easy access to healthcare.

In Delhi, 679 respondents aged 25 to 65 revealed that over 80% failed to identify blood in stool as a key symptom of colorectal cancer, highlighting a dangerous normalisation of digestive issues.

Self-Medication and Delayed Diagnosis

Many respondents reported turning to over-the-counter medicines, home remedies, or lifestyle changes rather than consulting a doctor for persistent bowel issues. According to the survey, nearly 90% of Delhi residents would first attempt self-treatment for constipation, loose motions, or other bowel changes lasting several weeks, with only 10% seeking medical advice.


Dr Shefali Sardana, medical oncology expert at Indraprastha Apollo Hospital, told TOI, “Blood in stool or persistent bowel irregularities are often brushed aside as minor issues. This delay significantly reduces the chances of early detection.”

Rising Risk Among Younger Adults

Colorectal cancer is no longer a disease only affecting the elderly. Around 40% of younger respondents admitted they ignored digestive irregularities, attributing them to lifestyle habits rather than potential medical concerns.

Dr Aditya Sarin, consultant medical oncologist at Sir Ganga Ram Hospital, said to TOI, “By the time it’s detected, it’s often already stage IV. Only 17.5% recognise blood in stool as a warning sign. This is not an old-age disease.”

Lifestyle Factors Contributing to Risk

The survey also shed light on lifestyle patterns that may be contributing to rising colorectal cancer cases in Delhi. Over 86% of respondents reported regular consumption of outside or packaged food, only 35.5% exercised regularly, and nearly 40% used tobacco.

Dr Sardana noted to TOI, “Most patients are unaware that colorectal cancer does not necessarily cause pain. They do not seek medical help until it starts hurting.”

Family History and Persistent Symptoms

Family history is another important risk factor. One in four respondents reported a family history of bowel cancer, polyps, or inflammatory bowel disease. More than 65% of respondents reported irregular bowel movements, while over 80% experienced sensations of incomplete evacuation at some point.

Dr Manish Singhal, medical oncologist at Yashoda Medicity, emphasised to TOI, “About 65,000 colorectal cancer cases are reported annually in India, and more than 50% result in death due to late detection. This could largely be avoided if people were aware of early symptoms.”

Key Takeaway: Do Not Ignore Digestive Symptoms

Despite the availability of healthcare in cities like Delhi, awareness about early colorectal cancer signs remains alarmingly low. Experts urge residents to seek medical consultation promptly if symptoms persist, particularly for those with a family history of bowel disease.

Dr Sarin concluded to TOI, “The message is simple: if symptoms persist, do not ignore them. Early detection saves lives.”
