WHO Warns Global Cancer Cases Could Nearly Double by 2050 Without Urgent Action

Quick Reads

• Global cancer cases could reach 35 million annually by 2050.
• Around 20.6 million new cancer cases and 10 million deaths occur each year.
• WHO says one in five people will develop cancer during their lifetime.
• Low- and middle-income countries face the greatest burden due to limited access to diagnosis and treatment.
• WHO is urging countries to invest in prevention, screening, affordable treatment, and people-centred cancer care.

The World Health Organization (WHO) has issued an urgent global warning that new cancer cases are on track to nearly double by 2050 unless countries take immediate action to strengthen prevention, diagnosis, treatment and long-term care.

According to the WHO Global Status Report on Cancer 2026, annual cancer diagnoses could rise from approximately 20.6 million today to nearly 35 million by 2050, driven by population growth, ageing populations and persistent exposure to major risk factors including tobacco use, obesity, alcohol consumption, unhealthy diets, physical inactivity and environmental pollution.

WHO estimates that one in every five people will develop cancer during their lifetime, while the disease already claims close to 10 million lives annually, making it one of the world’s leading causes of death.

Despite significant advances in cancer research and treatment over the past decade, the organization warned that access to lifesaving services remains deeply unequal. Many lower-income countries continue to struggle with shortages of essential medicines, radiotherapy facilities, trained health workers and comprehensive cancer programmes, leaving millions without timely diagnosis or treatment.

WHO said these disparities are widening the gap in cancer survival rates between wealthy and developing nations. In several low-income countries, patients face catastrophic healthcare costs, with many unable to access or complete treatment because of financial barriers.

To reverse the trend, WHO is calling on governments to adopt a people-centred approach that prioritizes prevention, expands vaccination and screening programmes, improves early detection, strengthens health systems and ensures equitable access to quality cancer care. The agency stressed that investments made today will determine whether future generations face an even greater global cancer burden.

Health experts also noted that many cancers remain preventable through proven public health measures such as tobacco control, HPV and hepatitis B vaccination, healthier lifestyles and earlier diagnosis, underscoring the importance of sustained investment in national cancer control strategies.
