Early cancer diagnosis saves lives, cuts treatment costs – WHO

by Manjari Peiris

Each year 8.8 million people die from cancer, mostly in low and middle income countries, the World Health Organization states. Late diagnosis is one problem and even in countries with optimal health systems and services, many cancer cases are diagnosed at an advanced stage, when they are harder to treat successfully.

Dr. Etienne Krug, Director of WHO's Department for the Management of non-communicable diseases, disability, violence and injury prevention states that many people unnecessarily suffer and succumb early death due to late diagnosis and the inability to provide treatment.

"By taking the steps to implement WHO's new guidance, healthcare planners can improve early diagnosis of cancer and ensure prompt treatment, especially for breast, cervical, and colorectal cancers. This will result in more people surviving cancer. It will also be less expensive to treat and cure cancer patients." he added.

The three steps to early diagnosis, according to WHO's new Guide are:-
• Improve public awareness of different cancer symptoms and encourage people to seek care when these arise.

• Invest in strengthening and equipping health services and training health workers so they can conduct accurate and timely diagnostics.

• Ensure people living with cancer can access safe and effective treatment, including pain relief, without incurring prohibitive personal or financial hardship.

Challenges are clearly greater in low- and middle-income countries, which have lower abilities to provide access to effective diagnostic services, including imaging, laboratory tests, and pathology – all key to helping detect cancers and plan treatment. Countries also currently have different capacities to refer cancer patients to the appropriate level of care.

WHO encourages these countries to prioritize basic, high-impact and low-cost cancer diagnosis and treatment services. The Organization also recommends reducing the need for people to pay for care out of their own pockets, which prevents many from seeking help in the first place.

Detecting cancer early also greatly reduces cancer’s financial impact: not only is the cost of treatment much less in cancer’s early stages, but people can also continue to work and support their families if they can access effective treatment in time. In 2010, the total annual economic cost of cancer through healthcare expenditure and loss of productivity was estimated at US$ 1.16 trillion.

Strategies to improve early diagnosis can be readily built into health systems at a low cost. In turn, effective early diagnosis can help detect cancer in patients at an earlier stage, enabling treatment that is generally more effective, less complex, and less expensive. For example, studies in high-income countries have shown that treatment for cancer patients who have been diagnosed early are 2 to 4 times less expensive compared to treating people diagnosed with cancer at more advanced stages.

Dr Oleg Chestnov, WHO Assistant Director-General for Non-communicable Diseases and Mental Health, notes: "Accelerated government action to strengthen cancer early diagnosis is key to meet global health and development goals, including the Sustainable Development Goals (SDGs)."
SDG 3 aims to ensure healthy lives and promote well-being for all at all ages. Countries agreed to a target of reducing premature deaths from cancers and other non-communicable diseases (NCDs) by one third by 2030.

They also agreed to achieve universal health coverage, including financial risk protection, access to quality essential health-care services, and access to safe, effective, quality and affordable essential medicines and vaccines for all. At the same time, efforts to meet other SDG targets, such as improving environmental health and reducing social inequalities can also help reduce the cancer burden.

Cancer is now responsible for almost 1 in 6 deaths globally. More than 14 million people develop cancer every year, and this figure is projected to rise to over 21 million by 2030. Progress on strengthening early cancer diagnosis and providing basic treatment for all can help countries meet national targets tied to the SDGs.

Most people diagnosed with cancer live in low- and middle-income countries, where two thirds of cancer deaths occur. Less than 30% of low-income countries have generally accessible diagnosis and treatment services, and referral systems for suspected cancer are often unavailable resulting in delayed and fragmented care.

The situation for pathology services was even more challenging: in 2015, approximately 35% of low-income countries reported that pathology services were generally available in the public sector, compared to more than 95% of high-income countries.

Comprehensive cancer control consists of prevention, early diagnosis and screening, treatment, palliative care, and survivorship care. All should be part of strong national cancer control plans. WHO has produced comprehensive cancer control guidance to help governments develop and implement such plans to protect people from the onset of cancer and to treat those needing care.
