Absolute risk is the excess number of observed cancers (or deaths) per 10,000 patients per year according to the formula: Absolute risk = [(observed - expected) / person-years] × 10,000.
Risks for all cancers and for leukemia or myelogenous leukemia exclude 3 cases of myelodysplastic syndrome because this disease is excluded from the general population rates published by S.E.E.R., which was used for these relative risk calculations.
