RESUMO
Analysis of cancer registration survival data, together with a review of published clinical and pathological studies, strongly suggests that cancer of the prostate occurring before the age of 55 has a worse survival prospect than at ages up to 74. The likely reasons appear to be a higher degree of malignancy of tumours in younger men and, particularly, late diagnosis from failure to suspect the disease in this age group. This suggests that routine clinical examination of the prostate should be carried out as soon as feasible after the age of 40.

An examination of Scottish cancer registration data over two five-year periods (1968-72, and 1973-77) shows a rise of about 1 1/2 times in incidence of acute myeloid leukaemia between the two periods. This finding is similar to that reported earlier in Lancashire. The increase has occurred at all ages, in all social classes, and in all parts of the country. Reasons why this increase is partially real are given.
