Young Adults Face Rising Colorectal Cancer Threat
6 Feb
Summary
- Colorectal cancer incidence is rising globally in adults under 50.
- Early-onset CRC rates in India are higher than in Western countries.
- India projects a doubling of CRC cases by 2050 due to lifestyle changes.
Colorectal cancer (CRC) rates are escalating globally among individuals under the age of 50. This concerning trend, often referred to as early-onset colorectal cancer (eoCRC), is particularly pronounced in high-income countries, with some European nations observing annual increases of up to 7.9% in young adults. In the United States, diagnoses in those under 55 have doubled over a decade, now representing 20% of all cases, frequently detected at advanced stages.
India mirrors this global concern, with studies indicating that 21-48% of CRC cases occur in patients under 40, a rate higher than Western figures. Data from a 2025 review analyzing CRC epidemiology in India reveals that CRC ranks as the fourth most common cancer, with an estimated 64,863 cases and 38,367 deaths. Incidence is increasing, especially colon cancer among urban females and rectal cancer in southern and northeastern regions.
Experts project that India could see a doubling of CRC cases by the year 2050. This anticipated rise is closely linked to significant shifts in lifestyle patterns across the country. The increasing prevalence of CRC in younger populations underscores the need for greater awareness and preventive measures.
