Summary

Project ID: 2023-1093/ TRIM 2025 0970 383 000

Principal Investigator: Jennifer Brooks

Description: In a cohort of women diagnosed with early-stage breast cancer between 2001 and 2020 in the province of Ontario the project team will:

1. Determine the incidence of contralateral breast cancer and other second primary cancers.
