It is usually deaths where cancer is mentioned as an underlying cause of deaths on death certificates.Cancer survival -. The percentage of people still alive after a specified amount of time, often 1, 5 or 10 years after a diagnosis of cancer at a specific time. It usually refers to primary cancers (secondary cancers or recurrences are not included).Median survivalis the length of time from the date of diagnosis that half of people diagnosed with cancer are still alive (or half have died). It is the time since diagnosis when relative survival is at 50%.Net survivalis the estimate of the number of people who survive their cancer, after removing the effects of a person dying from other causes (which is often referred to as background mortality).
