Cancer cases peak amid global decline: Study, Pg 8.

Key Highlights:

• Cancer incidence in India rose from 84.8 per 100,000 population in 1990 to 107.2 per 100,000 in 2023, totaling approximately 15 lakh cases.
• Cancer deaths in India increased from 71.7 per 100,000 in 1990 to 86.9 per 100,000 in 2023, reaching about 12.1 lakh deaths.
• Globally, cancer occurrence rates decreased from 220.6 per 100,000 in 1990 to 205.1 in 2023, and are projected to drop to 192.9 in 2025.
• Global cancer mortality rates fell from 150.7 per 100,000 in 1990 to 114.6 in 2023, with a further decrease expected to 107.9 in 2025.
• By 2050, cancer is projected to affect 30.5 million people and cause 18.6 million deaths worldwide, primarily in low and middle-income countries.

Detailed Insights:

• The rise in cancer cases and deaths in India and other lower-middle income countries highlights the need to strengthen healthcare systems to manage the increasing burden.
• A significant proportion of cancer deaths, around 42%, are linked to modifiable risk factors like tobacco and alcohol use, unhealthy diets, and poor management of hypertension and diabetes.
• Effective cancer control requires sustained public communication campaigns for early detection, involvement of all stakeholders, and evidence-based screening programs.
• India's high prevalence of obesity, diabetes, tobacco use, infections like HPV and Hepatitis B, and high pollution levels contribute to the increased cancer risk.
• Current non-communicable disease programs in India focus mainly on screening, necessitating a shift towards enhanced diagnosis and treatment interventions.

Key Concepts Involved:

• Cancer Incidence: The rate at which new cases of cancer occur in a population over a specific period.
• Cancer Mortality Rate: The proportion of deaths in a population caused by cancer within a specific time frame.
• Modifiable Risk Factors: Lifestyle or environmental factors that can be altered to reduce the risk of developing a disease.
