The formation of committees and other agencies for the study of cancer in many countries is leading to the collection of data that are of much interest and also in all likelihood of great significance.
As frequently noted, statistics in general seem to reveal an increase in cancer; but whether this may not be the outcome of greater accuracy in diagnosis is a question concerning which there is still a difference of opinion. Obviously, on the basis of the figures and facts now available, the solution of the question as to whether or not cancer is on the increase is most difficult. In the future the conditions for reliable comparisons will be more satisfactory.
