A new World Health Organization report delivers a stark WHO cancer warning, projecting that global cancer cases could rise to nearly 35 million by 2050. The report highlights widening disparities in prevention, diagnosis, treatment, and care, leaving millions without access to lifesaving services.
WHO projects sharp rise in global cancer burden
The World Health Organization says global cancer cases are expected to climb from an estimated 20.6 million annually to nearly 35 million by 2050, while inequities in cancer care continue to worsen despite advances in medical research.
The report estimates that one in five people will develop cancer during their lifetime, and 92% of the world’s population will be affected either through a personal diagnosis or that of a close family member.
“For years, the story told about cancer has been about scientific progress, new technologies, new treatment, new hope,” said Dr. Andre Ilbawi, team lead for cancer control at the WHO. “That story is true, and it deserves to be told, but it’s not the whole story.”
The annual global status report found persistent and widening gaps in access to prevention, early diagnosis, treatment and supportive care, particularly in low- and middle-income countries.
Report highlights wide gaps in access to cancer care
The report found survival rates vary sharply based on where patients live. In high-income countries, about 85% of people diagnosed with breast or childhood cancers survive at least five years. In poorer countries, survival falls below 30%.
Access to essential cancer medicines also differs widely. The WHO said only 9% to 54% of its top 20 priority cancer drugs are available in low- and lower-middle-income countries, compared with 68% to 94% in wealthier nations. The report also found 23 countries lack radiation therapy facilities.
Although cancer diagnosis rates are lower in sub-Saharan Africa than in wealthier regions, death rates remain disproportionately high because of delayed diagnosis and limited treatment options.
The WHO cancer warning underscores that two‑thirds of countries fail to include comprehensive cancer care in universal health coverage packages. High treatment costs push up to 90% of patients in some regions to abandon care, while a global patient survey reveals widespread financial hardship, mental health struggles, and caregiver strain.
Abigail Simon-Hart, a breast cancer survivor and patient advocate from Nigeria, said families often face impossible financial choices.
“I have seen parents choose between paying for treatment and keeping a child in school,” Simon-Hart said. She added that social stigma also discourages some patients from seeking lifesaving treatment.
WHO calls for equal focus on care and prevention
Despite the challenges, the WHO cancer warning also points to progress in several areas. Many countries now have national cancer action plans, global tobacco use continues to decline, and efforts to eliminate cervical cancer are steadily advancing.
Dr. Isabelle Soerjomataram, deputy head of the surveillance unit at the International Agency for Research on Cancer, said prevention remains a major opportunity.
“Four in 10 new cancer cases are linked to risk factors which we already know how to address,” she said, citing tobacco use, infections, alcohol consumption and excess body weight.
WHO experts urged governments and international partners to strengthen investment across the full spectrum of cancer care, from prevention and screening to diagnosis, treatment and palliative care. The report concludes that scientific breakthroughs alone will not reduce the global cancer burden unless access to quality care becomes more equitable.
