Experts stress need for early detection of colorectal cancer

Experts highlight urgent need for increased awareness of colorectal cancer signs, as many remain unaware of early warning signals.

Only 11.7% of residents in Chennai recognise blood in stool as a warning sign of colorectal cancer, according to a nationwide Lifestyle and Digestive Health Awareness Survey. The survey, supported by Merck Specialties Private Limited, covered 10,198 respondents aged between 25 and 65 across 14 major Indian cities. The findings were released as part of Colorectal Cancer Awareness Month in March.

City-specific data from Chennai, based on responses from 203 participants, revealed that 83.2% delay visiting a doctor when bowel habits change. More than half — 57.1% — reported experiencing irregular bowel movements, while 89.3% said they rely on self-medication or home remedies instead of seeking medical advice. Experts said these trends could lead to delayed diagnosis of colorectal cancer, which is largely treatable when detected early.

S. Subramanian, founder-chairman and managing director, VS Hospitals, Anita Ramesh, senior consultant medical oncologist, Kauvery Hospital, S. Rajasundaram, senior surgical oncologist, Iswarya Hospital, and S. Viswanath of Dr. Rela Institute and Medical Centre were present at the event held for the report’s release.

The survey found that over 80% of respondents across cities were unaware that blood in stool can be an early sign of colorectal cancer, underscoring the need for greater public awareness and early screening.
