INFOGRAPHIC | The forgotten cancers you should know about

Besides the more common breast, skin and lung cancers, there are a plethora of other cancers that are not as well-known.

  • Besides the more common breast, skin and lung cancers, there are many others 
  • Rare cancers make up 22% of all diagnosed cases in the world
  • In South Africa, before Covid-19, 9% of all deaths were due to cancer

Breast, lung, skin and prostate cancers are the ones most commonly reported in the media - with plenty of research funding and awareness about the signs to look out for.

There are, however, many other types of cancers that are not as well-known because they are less common. Rare cancers account for 22% of all cancers diagnosed worldwide, and they generally have a higher mortality rate.

Part of the reason for this is the lack of incentives from pharmaceutical companies to research these types of cancers. Studies, therefore, tend to be small and poorly funded.

In South Africa, about 9% of all pre-Covid-19 deaths were attributed to cancer, according to the health department. The most common cancers in 2014 for women were breast, cervix, colon, uterus and lung cancers. For men, the most common were cancers of the prostate, colon, lung, bladder and oesophagus. 

In children – in whom all cancers are considered rare – the most commons were acute leukaemia, brain tumours, nephroblastoma, neuroblastoma and non-Hodgkin lymphoma.
