Abstract

Results are presented of a long-term follow-up of patients with breast cancer seen in the Cambridge area from 1947 to 1950. After 21 years the survival curve of the breast-cancer patients runs parallel to the expected survival curve of a similar normal population. This suggests that 18 % of all the breast-cancer patients may be regarded as cured of their disease in the sense defined by Easson and Russell. 5 An analysis of the causes of death in the study group after 20 years' follow-up shows an excess of deaths from breast cancer. The number is 16 times more than would be expected in the normal population, although the overall death-rates in the two groups are the same. This questions the concept of cure.
