The World Health Organization (WHO) has issued a stark warning that the number of people diagnosed with cancer each year could rise dramatically over the next 25 years unless governments strengthen efforts to prevent the disease and improve access to treatment.
In its newly released Global Status Report on Cancer 2026, the WHO projects that annual cancer cases could increase from approximately 20.6 million recorded in 2024 to nearly 35 million by 2050. The organization says the surge is being driven by population growth, ageing populations, and increasing exposure to preventable risk factors such as tobacco use, harmful alcohol consumption, obesity, unhealthy diets, physical inactivity, and environmental pollution.
Unequal Access to Care Remains a Major Concern
While significant advances have been made in cancer diagnosis and treatment, the report emphasizes that millions of people, particularly in low- and middle-income countries, still lack access to quality cancer care.
According to the WHO, survival rates vary widely depending on where patients live. Many countries continue to face shortages of cancer specialists, diagnostic equipment, radiotherapy facilities, essential medicines, and affordable treatment options. Financial hardship also forces many patients to delay or completely abandon treatment.
WHO Director-General Dr. Tedros Adhanom Ghebreyesus stressed that no one should be denied life-saving cancer care because of where they live or their financial circumstances, urging countries to invest in stronger health systems and expand access to prevention, screening, diagnosis, treatment, rehabilitation, and palliative care.
Cancer Continues to Be One of the World’s Leading Killers
Cancer remains one of the leading causes of death globally, accounting for nearly 10 million deaths in 2024, according to WHO data. The most commonly diagnosed cancers include lung, breast, colorectal, prostate, stomach, and non-melanoma skin cancers. Lung cancer also remains the leading cause of cancer-related deaths worldwide.
Health experts note that one in five people worldwide is expected to develop cancer during their lifetime, highlighting the urgent need for stronger prevention and early detection programs.
Prevention Could Save Millions of Lives
Despite the concerning projections, WHO says a large proportion of cancer cases can be prevented through healthier lifestyles and effective public health policies.
The organization recommends:
- Avoiding tobacco products
- Limiting alcohol consumption
- Maintaining a healthy body weight
- Exercising regularly
- Eating a balanced diet rich in fruits and vegetables
- Receiving recommended vaccines such as HPV and hepatitis B
- Participating in routine cancer screening programs where available
Early detection remains one of the most effective ways to improve survival rates, particularly for breast, cervical, colorectal, and prostate cancers.
Challenges for Low- and Middle-Income Countries
The report highlights that countries with limited healthcare resources, including many across Africa, face some of the greatest challenges in responding to the growing cancer burden.
Limited diagnostic services, shortages of trained oncology professionals, delayed diagnoses, and high treatment costs continue to contribute to poorer outcomes. WHO is encouraging governments and international partners to prioritize cancer control by strengthening healthcare infrastructure, expanding screening services, and ensuring equitable access to treatment.
Looking Ahead
The WHO says the projected increase in cancer cases is not inevitable if countries take decisive action now. Investing in prevention, improving access to quality healthcare, promoting early diagnosis, and ensuring affordable treatment could save millions of lives over the coming decades.
As cancer continues to pose one of the world’s biggest public health challenges, global cooperation and sustained investment will be essential to reducing its impact and improving survival for future generations.
