The World Health Organization (WHO) reports that cancer remains the second leading cause of death globally, claiming more than 26,000 lives every day. With 20.6 million new cases diagnosed annually, projections indicate that cancer incidence could rise to nearly 35 million cases by 2050 without urgent action.
The Global Burden of Cancer
Cancer impacts nearly every household, whether through a personal diagnosis or that of a family member. According to the International Agency for Research on Cancer (IARC), the disease burden is not distributed evenly.
In 2024, Asia accounted for over 50% of all global cancer cases and 56.5% of deaths, largely due to population size. Europe faces a disproportionate burden, contributing 21% of cases despite representing only 9% of the world’s population. While incidence rates may be lower in parts of Africa and Asia, these regions often experience disproportionately high mortality rates, highlighting a critical gap in health infrastructure.
Persistent Inequities in Survival
A major finding in the WHO’s data is the stark survival gap between high-income and low-income countries. For women diagnosed with breast cancer, the five-year survival rate reaches 87% in high-income nations, compared to just 42% in low-income settings.
"Whether a person survives cancer should never depend on where they were born or what they earn," said WHO Director-General Dr. Tedros Adhanom Ghebreyesus. The report emphasizes that these inequities are not inevitable but are the result of policy choices that can be reversed through unified global action.
The Role of Preventable Risk Factors
Approximately four in ten cancer cases globally are linked to preventable risk factors. The WHO identifies several primary drivers:
- Infections: Human papillomavirus (HPV), hepatitis B and C, and Helicobacter pylori.
- Lifestyle Factors: Tobacco use, alcohol consumption, high body mass index and physical inactivity.
- Environmental Factors: Exposure to air pollution.
While tobacco use has declined by 27% since 2010, progress in reducing some cancer rates in countries that have implemented prevention policies has been too slow. Dr. Elisabete Weiderpass, Director of IARC, noted that the cancer profile is evolving, with rising rates of obesity, physical inactivity, unhealthy diets, and air pollution becoming major contributors to the global burden.
Financial and Social Impact
Beyond clinical outcomes, the economic toll of cancer is profound. The WHO’s first-ever survey on the subject found that at least 45% of people affected by cancer experience financial hardship. Additionally, more than half report mental health challenges, and caregivers frequently face social isolation and the strain of providing unpaid services.
Strategic Recommendations for Future Care
To address these challenges, the WHO advocates for a shift toward a people-centered approach. The report outlines three strategic shifts for nations to adopt:
- Better Capabilities: Integrating cancer control into universal health coverage and investing in human capital to prevent and control cancer.
- Better Protections: Placing people with lived experience at the centre of cancer systems while strengthening social protection.
- Better Value: Aligning research and innovation with public health needs and ensuring equitable access to valued-based advances in care.
Currently, fewer than one in three countries include cancer care in their universal health coverage packages. Furthermore, access to essential cancer medicines varies wildly; availability of the top 20 priority cancer medicines ranges from as low as 9% in low- and lower-middle-income countries to 94% in high-income nations. By fostering international collaboration and political commitment, the WHO argues that countries can reduce the cancer burden and improve long-term outcomes for all populations.
