Abstract
- Previous studies have reported substantially increased risks of breast cancer among survivors of childhood cancer at 10-20 years posttreatment. Whether these excess risks are sustained beyond 40 years of age when general population incidence of breast cancer begins its steep increase is largely unknown. We quantified the risk of breast cancer in adult female survivors with considerably more survivors followed-up beyond 40 years of age than previously available. Standardized Incidence Ratios (SIR), Excess Absolute Risks (EAR), and cumulative incidence were calculated within a population-based cohort of 8,093 female survivors of childhood cancer. Poisson regression models were used to model SIRs and EARs in a multivariable setting. Eighty-one survivors developed a primary breast cancer, where 37.5 were expected (SIR= 2.2, 95% CI: 1.7-2.7). SIRs decreased significantly with increasing attained age ( p [ABSTRACT FROM AUTHOR]
