Cancer is one of the most common causes of death worldwide. In several countries, it is the most common cause of death.
But which cancer types cause the most deaths?
The map presents the most common type of cancer death among men. This is based on the cause listed on death certificates, compiled by the WHO Mortality Database. Unfortunately, many countries are not shown as they lack sufficient death registration.
Lung cancer is the leading cause of male cancer deaths in many countries, primarily driven by smoking.
In parts of Latin America, prostate cancer leads. Although it has high survival rates in richer countries, it is common and can reach late stages before diagnosis, which limits treatment options.
Stomach cancer — shown in purple on the map — is the leading cause in several Central Asian countries. It is primarily caused by H. pylori infections. In wealthier countries, infections have declined thanks to better food safety, hygiene, and antibiotics.
Liver cancer, leading in Mongolia, Thailand, and Egypt, is often the result of inflammation caused by long-term alcohol consumption or hepatitis virus infection.
