Around one third of deaths from cancer are due to the 5 leading behavioral and dietary risks:

  1. high body mass index,
  2. low fruit and vegetable intake,
  3. lack of physical activity,
  4. tobacco use, and
  5. alcohol use.

Late-stage presentation and inaccessible diagnosis and treatment are common. In 2017, only 26% of low-income countries reported having pathology services generally available in the public sector. More than 90% of high-income countries reported treatment services are available compared to less than 30% of low-income countries.

Only 1 in 5 low- and middle-income countries have the necessary data to drive cancer policy.

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.

This is largely because these countries have had to focus limited health resources on combating infectious diseases and improving maternal and child health, while health services are not equipped to prevent, diagnose and treat cancers. 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.

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.
