[Social inequality and incidence of and survival from cancer in Denmark--secondary publication].

This register-based study describes social variations in cancer incidence and survival in 3.22 million Danish residents born 1925-1973 and aged >or= 30 years. We followed up for cancer incidence in 1994-2003 and for survival in 1994-2006, yielding 147,973 cancers. The incidence increased with lower education and income, especially for tobacco- and other lifestyle-related cancers. Social inequality in the prognosis of most cancers was observed, with poorer relative survival related to fewer advantages, often most pronounced in the first year after diagnosis.
