India carries one of the heaviest global burdens of cancer. According to the Global Cancer Care Observatory, the country ranked third in total cases in 2022, with a mortality-to-incidence ratio of 64.47%—the highest among the top 10 affected nations. Despite cancer being part of national health programmes for over five decades, interventions have often struggled due to a lack of comprehensive, reliable data.
The Indian Council of Medical Research (ICMR) launched its cancer registry programme in the early 1980s, but these registries currently cover less than 20% of the population. A recent analysis of 43 registries offers valuable insights, identifying not just the most common cancers but also regional and gender-based vulnerabilities. This evidence could finally help bridge the gap in India’s cancer map.
What the Data Shows
- Gender trends: Women account for 51% of cases in registries, bucking global patterns. The higher reporting is linked to breast and cervical cancers, which together make up over 40% of cases among women and are relatively easier to detect and treat.
- Hidden burden: Oral, lung, and gastric cancers—more common among men—are often detected late, with many cases still unreported.
- Regional disparities: The Northeast carries a disproportionately high burden, with Mizoram showing lifetime risks of 21% for men and 19% for women, nearly double the national average.
These findings highlight the need for region-specific screening and awareness campaigns, such as oral cancer initiatives in the Northeast, Ahmedabad, and Bhopal.
Why Robust Data Matters
Unlike infectious diseases such as tuberculosis, healthcare providers in most states are not legally required to share cancer data. Only 17 states mandate reporting, leaving out populous regions like Uttar Pradesh, Maharashtra, and Bihar. Without stronger registry coverage, national cancer control efforts will remain fragmented.
Expanding mandatory reporting and strengthening the registry system would help:
- Identify preventable causes more effectively.
- Ensure better resource allocation for screening and treatment.
- Improve survival rates by enabling earlier detection.
The Way Forward
India cannot afford to fight cancer blindfolded. The registry study is a crucial first step, but policymakers must follow through by building a robust, nationwide data framework. Accurate mapping will allow targeted programmes, reduce preventable deaths, and strengthen India’s fight against one of its most pressing health challenges.
