WHO report finds vast gap in breast cancer survival

The World Health Organization published the first-ever global breast cancer survival estimates on July 8, showing that a woman's chance of surviving the disease depends heavily on where she lives and how much her country earns. The data, released alongside the WHO Global Status Report on Cancer 2026, found that five-year survival rates range from an average of 39.1% in the WHO African Region to 88.5% in the WHO Region of the Americas.iarc.who+1

The findings, produced by researchers at the International Agency for Research on Cancer and published in Nature Medicine, estimated population-based survival for women diagnosed with breast cancer between 2017 and 2021 across all 194 WHO Member States. While 87% of women with breast cancer survive at least five years in high-income countries, only about 42% do so in low-income countries, according to the WHO.who+2

A Growing Global Burden

Breast cancer caused an estimated 694,000 deaths globally in 2024, with roughly 70% occurring in low- and middle-income countries. The survival estimates were released as part of a broader WHO assessment warning that annual cancer cases worldwide could rise to nearly 35 million by 2050 without urgent action.news.un+2

"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 inequities documented in this report are not inevitable; they are the consequence of choices, and they can be reversed through stronger and unified action."who

Barriers to Care

The report identified stark gaps in access to essential cancer medicines, with availability of the top 20 priority cancer medicines ranging from just 9% to 54% in low- and lower-middle-income countries, compared with 68% to 94% in high-income countries. Fewer than one in three countries currently include cancer care in their universal health coverage packages.who

The survival data now serves as a baseline for the WHO Global Breast Cancer Initiative, which has set targets of diagnosing at least 60% of invasive breast cancers at stage I or II, completing diagnostic evaluation within 60 days, and ensuring at least 80% of patients complete treatment — all by 2040.iarc.who

Prevention and the Path Forward

Nearly four in ten cancer cases globally are linked to preventable risk factors, including infections, tobacco use, alcohol consumption, and high body mass index. Tobacco use has declined 27% since 2010, and 82% of countries now have national cancer control plans, up from 50% in 2010. But the WHO warned that progress is not translating into action fast enough, particularly in lower-income settings where cancer mortality remains disproportionately high.healthpolicy-watch+1
