The world is facing a growing cancer crisis that could see annual new cases rise to nearly 35 million by 2050 unless governments take urgent and coordinated action, the World Health Organisation (WHO) has warned.

In its newly released Global Status Report on Cancer 2026, produced jointly with the International Agency for Research on Cancer (IARC), the UN health agency paints a sobering picture of a disease that already claims more than 26,000 lives every day and remains the world's second leading cause of death, after cardiovascular disease.

According to the report, the world currently records an estimated 20.6 million new cancer cases and nearly 10 million deaths each year. Without stronger investment in prevention, diagnosis, treatment and supportive care, that burden is expected to increase dramatically over the coming decades.

A Crisis Beyond the Hospital

Cancer is often viewed primarily as a medical condition, but the WHO report highlights its far-reaching human and economic consequences.

Beyond the physical impact of the disease, cancer places enormous emotional and financial strain on patients and their families. WHO's first global survey of people living with cancer found that nearly half experience financial hardship, while more than half report mental health challenges. Caregivers also face significant emotional stress, unpaid responsibilities, and social isolation.

WHO Director-General Dr. Tedros Adhanom Ghebreyesus said survival should never depend on geography or income.

"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."

He described the inequalities highlighted in the report as preventable and urged governments to strengthen health systems through coordinated action.

The Inequality Gap

One of the report's most alarming findings is the stark disparity in cancer outcomes between high-income and low-income countries.

For example, while 87% of women diagnosed with breast cancer survive for at least five years in high-income countries, the survival rate falls to about 42% in low-income countries.

Access to treatment also remains highly unequal.

The report notes that fewer than one in three countries currently include comprehensive cancer care within their universal health coverage packages, leaving millions without affordable diagnosis or treatment.

Availability of essential cancer medicines is also significantly lower in low- and lower-middle-income countries compared with wealthier nations.

What This Means for Africa

Although Africa currently records fewer cancer cases than many other regions because of its younger population, mortality rates remain disproportionately high.

Limited access to early diagnosis, specialist care, radiotherapy, chemotherapy, pathology services, and essential medicines means many cancers are detected at advanced stages, when treatment is more difficult and less successful.

For countries such as Nigeria, health experts say strengthening primary healthcare, improving cancer screening programmes, expanding specialist services, and increasing public awareness will be essential to reducing preventable deaths.

Many Cancers Can Be Prevented

The WHO report estimates that nearly four out of every ten cancer cases worldwide are linked to preventable risk factors.

Among the leading contributors are:

• Tobacco use

• Harmful alcohol consumption

• Obesity

• Physical inactivity

• Unhealthy diets

• Air pollution

• Infections such as Human Papillomavirus (HPV), hepatitis B and C, and Helicobacter pylori

Health experts say reducing these risk factors through stronger public health policies, vaccination programmes, healthier lifestyles, and improved environmental protection could significantly lower future cancer rates.

Progress Worth Building On

Despite the challenges, the report also highlights encouraging developments.

Global tobacco use has fallen by 27% since 2010, helping reduce lung cancer rates in several countries.

Vaccination programmes against HPV and hepatitis B are lowering the incidence of infection-related cancers, while improvements in water, sanitation, hygiene, and infection control have also contributed to better health outcomes.

Political commitment has strengthened as well. More than 80% of countries now have national cancer control plans, compared with only half in 2010.

Scientific innovation continues to accelerate, with cancer clinical trials increasing steadily over the past two decades.

A Call for People-Centred Care

The WHO is urging governments, healthcare providers, researchers, civil society organisations, and development partners to place people living with cancer at the centre of policy decisions.

The report recommends integrating cancer services into universal health coverage, investing in healthcare workers, strengthening social protection for patients and families, and ensuring that advances in research and treatment are accessible to all—not only those who can afford them.

It also calls for closer collaboration between policymakers and people with lived experience of cancer, arguing that effective solutions must reflect the realities faced by patients and caregivers.

Why It Matters

Cancer is no longer a challenge affecting only wealthier nations.

It is a growing global health issue with profound consequences for families, communities, and national economies.

For Nigeria and other developing countries, rising cancer rates underscore the importance of investing in prevention, expanding access to affordable healthcare, improving early detection, and ensuring that treatment is available regardless of income or place of residence.

The choices governments make today, the WHO warns, will determine how many lives can be saved in the decades ahead.
