Childbearing and Survival After Breast Cancer
Abstract
An increase in breast cancer incidence among younger women has been observed, thus many young breast cancer patients are faced with questions concerning their reproductive futures. At present it is unclear whether attempting childbearing may increase these women's risk of death. This project obtained data from a large sample of women to compare relative survival of women with and without births among young women with breast cancer. Data were obtained from three population based registries (the Surveillance, Epidemiology, and End Results, or SEER Registries, in Seattle, Detroit, and Los Angeles). All women less than 45 years of age, diagnosed with breast cancer were identified in each of the three study regions. Their records were linked with birth certificates from each state to identify those (about 3%-4%) with a live birth after their initial diagnosis with breast cancer. Comparison subjects were identified from among young women with breast cancer in each region without subsequent births, matched on age and stage of disease at diagnosis, diagnosis year, race, and presence of multiple primary tumor. Date of last follow up and vital status for all subjects are being updated from several sources, and relative survival will be compared among these two groups.
