This is a clear, well written paper providing a quantification for a well known association between social class and/or education and risk of selected cancers. ------------------------------------------------------------------------------- 
Major Compulsory Revisions (that the author must respond to before a decision on publication can be 
reached)

Minor Essential Revisions (such as missing labels on figures, or the wrong use of a term, which the author 
can be trusted to correct) 1)In the Results the authors use the abbreviation "SES" without definition 2)Figure 1 and 2: it would be preferable to use the cancer anatomical site rather than a,b,or c. The lines 
indicating the incident rates should be different for the four levels of social class, while they appears the
