Alarming Study: Most Indian Colorectal Cancers Found Late
8 Mar
Summary
- Majority of patients diagnosed at Stage III or IV.
- Nearly 30% of patients were younger than 45 years.
- Fewer than 10% of eligible Indians undergo screening.
A recent study from Bengaluru's Kidwai Memorial Institute of Oncology highlights that the majority of colorectal cancer cases in India are detected only in advanced stages. Analysis of 831 patients between January 2021 and February 2025 showed 58% diagnosed at Stage III and 25.5% at Stage IV.
The findings also indicate a troubling increase in early-onset colorectal cancer, with nearly 30% of patients being younger than 45. This reflects a broader national trend where delayed diagnosis significantly impacts treatment outcomes, emphasizing the urgent need for enhanced screening and public awareness initiatives.
Published in the South Asian Journal of Cancer on February 26, 2026, the research also identified specific patterns in Indian patients, including a higher prevalence of aggressive tumor subtypes. Gender differences were noted, with women more likely to be diagnosed at later stages.
Experts attribute the rising incidence to lifestyle changes, including sedentary habits and dietary shifts. A significant gap in preventive care persists, with fewer than 10% of eligible Indians undergoing screening, allowing many cancers to go undetected until they are advanced.
