This is a list of countries by cancer frequency, as measured by the number of new cancer cases per 100,000 population among countries, based on the 2018 GLOBOCAN statistics and including all cancer types (some earlier statistics excluded non-melanoma skin cancer).
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body.

The 5-year observed survival rate refers to the percentage of patients who live at least five years after being diagnosed with cancer. Many of these patients live much longer than five years after diagnosis.
The most common as of 2018 are lung cancer (1.76 million deaths), colorectal cancer (860,000) stomach cancer (780,000), liver cancer (780,000), and breast cancer (620,000). [2] This makes invasive cancer the leading cause of death in the developed world and the second leading in the developing world . [ 19 ]
Cancer related to one's occupation is believed to represent between 2–20% of all cases. [17] Most cancer deaths caused by occupational risk factors occur in the developed world.

The age-adjusted death rate from cancer per 100,000 inhabitants in 2004. [1] The epidemiology of cancer is the study of the factors affecting cancer, as a way to infer possible trends and causes. The study of cancer epidemiology uses epidemiological methods to find the cause of cancer and to identify and develop improved treatments.
