As the number of people living to reach old age increases, so the proportion of cancers presenting in this age group increases to an even greater degree. Although 70% of all cancers in men and women occur over the age of 65 and in the over-75s, who are perhaps more appropriately classified as ‘elderly’, the figures are still very high (46% of all cancers occur in women over 75 and 35% in men over 75). As a consequence, cancer is rapidly becoming a problem of late life, and the management of patients in old age is an important part of general oncology. The magnitude of the overlap between old age and cancer is increasing because of improved life expectancy, more sensitive methods of diagnosing cancer and the biological fact that most cancers occur more commonly with increasing age. It is interesting, however, to put these figures into a more general context by examining the different causes of death in older patients by decade.
