Introduction

Cancer has emerged as one of India’s most pressing public health challenges. According to the World Health Organization (WHO), 30% to 50% of cancers are preventable through lifestyle changes and evidence-based interventions. Yet, India witnessed 15.6 lakh new cancer cases and 8.74 lakh deaths in 2024. Data from population-based cancer registries covering 10–18% of the population across 23 states provides crucial insights into trends, regional variations, and policy gaps.

Trends in Cancer Incidence

Gender Disparities

• Women account for 51.1% of cancer cases but only 45% of deaths.

• Common cancers in women (breast and cervical) are relatively easier to detect and treat.

• In contrast, men suffer more from lung and gastric cancers, which are harder to detect early and have poorer outcomes.

Oral Cancer Rising

• Oral cancer has overtaken lung cancer as the most common cancer in men.

• Tobacco use has declined from 34.6% to 28.6% (2009–2017), but due to long latency periods and other factors such as alcohol consumption, incidence remains high.

• Combined use of tobacco and alcohol compounds cancer risk significantly.

Regional Variations – Northeast at the Forefront

• The highest incidence of cancer is in the Northeast, with Mizoram showing a lifetime risk of 21.1% for men and 18.9% for women—almost double the national average.

• Factors include:

  • High tobacco use among men and women.

  • Dietary habits (smoked meat/fish, fermented pork fat, spicy foods, hot beverages).

  • High prevalence of infections like Helicobacter pylori, HPV, and hepatitis.

Significance of the Findings

Policy Planning and Healthcare Infrastructure

• Data can guide both Centre and states in cancer care planning, including:

  • Targeted screening at primary health centres.

  • Specialised treatment under Ayushman Bharat.

  • Strengthening cancer care in high-incidence regions like the Northeast.

Role of Early Detection and Awareness

• Breast cancer (30% of female cases) can be effectively managed if detected early.

• Cervical cancer still remains above 4 per 100,000 in most registries, highlighting the urgent need for:

  • HPV vaccination.

  • Large-scale screening programmes.

  • Awareness campaigns focusing on rural and vulnerable groups.

Preventive Measures and WHO Guidelines

• WHO stresses that 30–50% of cancers can be prevented by addressing risk factors such as tobacco, alcohol, diet, infections, and obesity.

• Early diagnosis, timely treatment, and palliative care significantly improve survival rates.

Challenges Ahead

1. Limited Coverage of Cancer Registries

   • Current data covers only 10–18% of the population, leaving major gaps.

2. Lifestyle and Socio-Behavioural Barriers

   • Tobacco and alcohol consumption remain entrenched, especially in rural and tribal communities.

3. Healthcare Inequalities

   • Rural areas lack adequate screening and treatment facilities.

   • High cancer burden in the Northeast coincides with weak infrastructure.

4. Digital Divide in Healthcare

   • While telemedicine and digital health can assist, poor connectivity in rural India restricts reach.

Way Forward

• Strengthen Cancer Registries to cover the entire population for better data-driven policies.

• Invest in Screening and Vaccination: Expand HPV vaccination and nationwide breast/cervical cancer screening.

• Focus on High-Risk Regions: Build cancer care centres and train healthcare workers in the Northeast.

• Behavioural Interventions: Promote anti-tobacco, anti-alcohol campaigns and awareness on diet and lifestyle.

• Integrated Cancer Care: Develop comprehensive programmes under Ayushman Bharat with equal emphasis on prevention, early detection, treatment, and palliative care.

• Community Participation: Local leaders, NGOs, and civil society must be involved in awareness and behavioural change.

Conclusion

India’s cancer map underlines that the disease is not merely a medical concern but a social, behavioural, and policy challenge. Addressing it requires a holistic strategy—strengthening registries, scaling screening and vaccination, improving regional infrastructure, and transforming lifestyle habits. The goal must be to ensure that cancer care is preventive, affordable, inclusive, and equitable, reflecting India’s constitutional commitment to health as a public good.
