4 February 2020- GENEVA / WASHINGTON, DC—The World Health Organization (WHO) today spells out the need to step up cancer services in low and middle-income countries. WHO warns that, if current trends continue, the world will see a 60% increase in cancer cases over the next two decades. The greatest increase (an estimated 81%) in new cases will occur in low- and middle-income countries, where survival rates are currently lowest.

Poster I am I willThis is largely because these countries have focused limited health resources on combating infectious diseases and improving maternal and child health, while health systems do not have the capacity to adequately prevent, screen, diagnose and treat people with cancer. In 2019, more than 90% of high-income countries reported that comprehensive treatment services for cancer were available in the public health system compared to less than 15% of low-income countries.

“This is a wake-up call to all of us to tackle the unacceptable inequalities between cancer services in rich and poor countries,” says Dr Tedros Adhanom Ghebreyesus, Director-General, WHO. “If people have access to primary care and referral systems then cancer can be detected early, treated effectively and cured. Cancer should not be a death sentence for anyone, anywhere.”

Yet, progress in poorer countries is achievable. WHO and the International Agency for Research on Cancer (IARC) are releasing two coordinated reports on World Cancer Day (4 February), in response to government calls for more research into the scope and potential policies and programmes to improve cancer control.

“At least 7 million lives could be saved over the next decade, by identifying the most appropriate science for each country situation, by basing strong cancer responses on universal health coverage, and by mobilizing different stakeholders to work together”, explained Dr Ren Minghui, Assistant Director-General, Universal Health Coverage/ Communicable and Noncommunicable Diseases, World Health Organization.

WHO highlights a wide range of proven interventions to prevent new cancer cases. These include controlling tobacco use (responsible for 25% of cancer deaths), vaccinating against hepatitis B to prevent liver cancer, eliminating cervical cancer by vaccinating against HPV, screening and treatment, implementing high-impact cancer management interventions that bring value for money and ensuring access to palliative care including pain relief.

"The past 50 years have seen tremendous advances in research on cancer prevention and treatment,” says Dr Elisabete Weiderpass, Director of IARC. “Deaths from cancer have been reduced. High-income countries have adopted prevention, early diagnosis and screening programmes, which together with better treatment, have contributed to 21% reduction in premature mortality between 2000 and 2015, but low-income countries only saw a reduction of 6%. We need to see everyone benefitting equally.”​

The challenge will be for countries to select treatments balancing considerations including cost, feasibility and effectiveness. It will be important to recall that newer treatments may have only marginal benefits over older, very effective, cost-effective, and more affordable off-patent medicines.

“In the Americas region, the Pan American Health Organization (PAHO), is working to increase access to essential medicines for cancer treatment through the PAHO Strategic Fund. This offers a pooled procurement mechanism for high quality and cost effective essential medicines, including for cancer treatment,” said PAHO Director Dr Carissa Etienne.

Cancer in the Americas

In the Americas, cancer is the second leading cause of death. In 2018, an estimated 3.8 million people were diagnosed, and 1.4 million people died from the disease. Approximately, 57% of cases and 47% of cancer deaths occurred in people age 69 years and younger.

The most frequently diagnosed types of cancer among men are prostate (21.7%), lung (9.5%), colorectal (8%), and bladder (4.6%). Among women, the most common cancers are: breast (25.2%), lung (8.5%), colorectal (8.2%), and thyroid (5.4 %). Despite that it can be eliminated through HPV vaccination, and screening and treatment of pre-cancerous lesions, cervical cancer is one of the most common cancer among women in Latin America and the Caribbean.

The type of cancers with the highest mortality rates in men are lung (19.6%), prostate (12.1%), colorectal (9.3%), liver (6%) and stomach (5.4%). The cancers that cause the most deaths among women are lung (17.4%), breast (15.1%), colorectal (9.5%) and cervical (5.2%).

It is anticipated that by 2030, the number of people newly diagnosed with cancer will increase by 32% to more than 5 million people each year in the Region, due to the aging population, and exposure to risk factors, among other issues.

PAHO is working with Ministries of Health to improve prevention, screening, diagnosis, and access to treatment for all people in the Region of the Americas.

Note to editors

World Health Organization

Report on Cancer: Setting priorities, investing wisely and providing care for all 
The report aims to set the global agenda on cancer, mobilize stakeholders and help countries set priorities for investing in cancer control and universal health coverage. It introduces the principles, tools and current priority cancer control interventions in the context of the current and future cancer burden and opportunities.

International Agency for Research on Cancer

World Cancer Report “Cancer research for cancer prevention”
The report focuses on prevention and offers the most comprehensive overview of relevant research available to date, ranging from descriptive etiology, cellular and molecular biology, toxicology and pathology through to behavioural and social science. Key chapters include discussions on the impact of inequalities in cancer, vaccination and screening, genomic individual susceptibility to cancer and the finer identification of those at risk, which may allow ‘precision cancer prevention’.
