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.

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.

New guidance from WHO, launched ahead of World Cancer Day (4 February), aims to improve the chances of survival for people living with cancer by ensuring that health services can focus on diagnosing cancer and treating the disease earlier.

New WHO figures released this week indicate that each year 8.8 million people die from cancer, mostly in low- and middle-income countries. One problem is that many cancer cases are diagnosed too late. 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.

“Diagnosing cancer in late stages, and the inability to provide treatment, condemns many people to unnecessary suffering and early death,” says Dr Etienne Krug, Director of WHO’s Department for the Management of Noncommunicable Diseases, Disability, Violence and Injury Prevention.

“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.”

All countries can take steps to improve early diagnosis of cancer, according to WHO’s new Guide to cancer early diagnosis.

The three steps to early diagnosis 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.

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.

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 Noncommunicable 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 noncommunicable 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.
