Cancer in India: WHO Report Reveals 1 in 10 Indians at Risk before Age 75

Why in News ?

• According to the WHO Global Status Report on Cancer 2026 and GLOBOCAN 2022, cancer is emerging as one of India's biggest public health challenges.
• Nearly 1 in every 10 Indians is likely to develop cancer before the age of 75 years, while about 7 in every 100 Indians face the risk of dying from cancer before reaching that age.
• Experts estimate that India's annual cancer cases could rise to 2.8 million by 2050.

Key Highlights

Why Are Cancer Cases Rising in India ?

The increase in cancer cases is driven by multiple demographic, lifestyle and environmental factors.

1. Ageing Population

• Life expectancy has increased significantly.
• Since cancer is primarily an age-related disease, more elderly people mean more cancer cases.

2. Lifestyle Changes

• Rising obesity
• Unhealthy diets
• Physical inactivity
• Alcohol consumption
• Tobacco use
• Stressful urban lifestyles

3. Tobacco Consumption

• Smoking is the leading cause of lung cancer.
• Smokeless tobacco products such as gutkha, khaini and betel quid have made India one of the countries with the highest burden of oral cancer.

4. Air Pollution

• Long-term exposure to polluted air increases the risk of lung and several other cancers.

5. Improved Diagnosis

• Better screening and diagnostic facilities have increased cancer detection.
• However, improved diagnosis alone does not explain the rapid rise in cases.

Major Types of Cancer in India

• According to GLOBOCAN 2022:

Among Women

• Breast cancer is the most common cancer.
• Cervical cancer remains the second most common despite being largely preventable.

Among Men

• Lip and oral cavity cancer is the leading cancer due to widespread tobacco consumption.

Emerging Concern

• Colorectal cancer is increasing because of ageing, unhealthy diet and sedentary lifestyle.

Major Risk Factors

• Tobacco use
• Alcohol consumption
• Obesity
• Physical inactivity
• Unhealthy diet
• Air pollution
• Ageing population
• Family history
• Viral infections such as Human Papillomavirus (HPV) and Hepatitis B

Importance of Prevention

Health experts believe that a significant proportion of cancers can either be prevented or detected early.

Key Preventive Measures

• Strong tobacco control
• HPV vaccination
• Routine screening for breast, cervical and oral cancers
• Healthy diet
• Regular physical activity
• Limiting alcohol consumption
• Awareness of early warning signs
• Timely diagnosis

Why Early Diagnosis Matters

• Many cancer patients in India reach hospitals only after the disease has advanced.
• Late diagnosis results in :
  • Lower survival rates
  • Higher treatment costs
  • More complicated treatment
  • Poor quality of life

Challenges Before India's Healthcare System

• According to the WHO Global Status Report on Cancer 2026 :
  • Around 45% of cancer patients face financial hardship.
  • More than half experience mental health challenges.
  • Caregivers suffer emotional, social and financial stress.
  • Many families experience catastrophic healthcare expenditure.
  • Large disparities exist in access to cancer care between urban and rural areas.
  • Access to essential cancer medicines remains unequal.

Government of India Initiatives

• National Programme for Prevention and Control of Non-Communicable Diseases (NP-NCD)
• Ayushman Bharat–Pradhan Mantri Jan Arogya Yojana (AB-PMJAY)
• Ayushman Arogya Mandirs for screening and early detection
• National Tobacco Control Programme (NTCP)
• Expansion of HPV vaccination
• Strengthening Regional Cancer Centres and tertiary care hospitals

What is Cancer? (According to WHO)

• Cancer is a large group of diseases that can begin in almost any organ or tissue of the body.
• It is characterized by the uncontrolled growth of abnormal cells, which can invade nearby tissues and spread to other parts of the body (metastasis).
• Cancer is the second leading cause of death worldwide.
• Globally, one in every six deaths is caused by cancer.

Need for Cancer Awareness

• Cancer is a disease that is often curable if detected at an early stage.
• In many cases, people are unaware of the early warning signs and symptoms of cancer.
• As a result, the disease is often diagnosed at an advanced stage, making treatment more difficult and reducing the chances of survival.

Major Symptoms of Cancer

• Unexplained weight loss
• Persistent or unusual pain
• Continuous cough
• Unexplained bleeding or blood discharge
• Formation of a lump or swelling
• Other persistent abnormal symptoms

Cancer Treatment

• The choice of treatment depends on the type and stage of cancer.
• In many cases, a combination of treatment methods is used, including :
  • Surgery
  • Chemotherapy
  • Radiation Therapy
  • Immunotherapy
  • Targeted Therapy
  • Hormone Therapy
  • Stem Cell/Bone Marrow Transplant (where required)

Way Forward

• Strengthen nationwide cancer screening programmes.
• Expand HPV vaccination coverage.
• Intensify tobacco control measures.
• Improve awareness regarding lifestyle modification.
• Ensure affordable access to cancer diagnosis and treatment.
• Reduce rural-urban disparities in healthcare.
• Promote people-centred cancer care with psychological, financial and social support.
• Increase investment in oncology infrastructure, research and skilled manpower.

Conclusion

Cancer is rapidly becoming one of India's most serious public health challenges. With annual cancer cases projected to reach 2.8 million by 2050, India must shift its focus from treatment alone to prevention, early detection and equitable healthcare access. Strengthening screening programmes, reducing tobacco use, expanding vaccination, and improving healthcare infrastructure will be essential to reducing the country's future cancer burden.
