WHO Warns Global Cancer Cases Could Reach 35 Million Annually by 2050

Annual new cancer cases worldwide are projected to rise to nearly 35 million by 2050 without urgent action to improve prevention, early detection, treatment access, and supportive care, according to a new report from the World Health Organization and the International Agency for Research on Cancer.¹

The WHO Global Status Report on Cancer 2026 estimates that 20.6 million people received a cancer diagnosis worldwide in 2024, including nonmelanoma skin cancers, and nearly 10 million people die of cancer each year. Cancer remains the second leading cause of death globally after cardiovascular disease, according to WHO, claiming more than 26 000 lives each day.¹

The report frames cancer as a near-universal disease with highly inequitable outcomes. One in 5 people will develop cancer in their lifetime, and when the effect on close family members is included, WHO estimates that approximately 92% of the global population will be affected by cancer at least once during their lifetime.¹

“Cancer is a deeply personal disease that touches nearly all of us. But whether a person survives cancer should never depend on where they were born or what they earn,” WHO Director-General Tedros Adhanom Ghebreyesus, PhD, MSc, said in a press release. “The inequities documented in this report are not inevitable; they are the consequence of choices, and they can be reversed through stronger and unified action.”²

The survival gaps are substantial. According to WHO, 5-year survival for breast cancer exceeds 85% in high-income countries but falls below 45% in low-income countries. The report noted that breast cancer 5-year survival is 87% in high-income countries compared with approximately 42% in low-income countries.¹

The report also found that cancer imposes major financial and psychosocial burdens. WHO’s global survey of people affected by cancer found that at least 45% experience financial hardship, more than half report mental health challenges, and nearly all caregivers report strain, including unpaid services and social isolation.¹

Cancer burden varies across regions. In 2024, Asia accounted for 50.7% of all cancer cases and 56.5% of cancer deaths, reflecting its large population. Europe accounted for 21% of cases and 20% of deaths despite representing approximately 9% of the global population. Many countries in Africa and parts of Asia have lower cancer incidence but disproportionately high mortality, reflecting gaps in timely diagnosis and treatment access.¹

WHO emphasized that prevention remains critical. Nearly 4 in 10 cancer cases globally are linked to preventable risk factors, including infections such as human papillomavirus, hepatitis B and C, and Helicobacter pylori; tobacco use; alcohol use; high body mass index; and insufficient physical activity.¹

There has been measurable progress. Tobacco use has declined by 27% since 2010, and 82% of countries now have national cancer control plans, up from 50% in 2010. HPV vaccination has been integrated into national immunization programs in 85% of countries, although global first-dose HPV vaccine coverage among girls is estimated at 31%, well below the 90% target for 2030.¹

Despite these gains, the report identified major implementation gaps. Only 28% of countries include a minimum cancer management package in universal health coverage benefit packages. Availability of priority cancer medicines also remains uneven, ranging from 9% to 54% in low- and lower-middle-income countries compared with 68% to 94% in high-income countries.¹

The report calls for a people-centered cancer control agenda built around 3 strategic shifts: better capabilities, including integration of cancer control into universal health coverage and health system strengthening; better protections, including social protections and engagement of people with lived experience; and better value, including research and innovation aligned with public health needs and equitable access.¹

For primary care clinicians, the report reinforces the importance of prevention, vaccination, early recognition of cancer warning signs, risk-factor counseling, and timely referral for screening, diagnostic evaluation, and survivorship support. The findings also underscore the need to consider the financial, emotional, and caregiver burden of cancer as part of routine care.¹

“The cancer profile is evolving, increasingly driven by rising rates of obesity, physical inactivity, unhealthy diets, and air pollution,” Elisabete Weiderpass, MD, PhD, director of IARC, said in the announcement. “Cancer prevention must remain a political priority.”²
