This risk calculator calculates the risk of breast cancer in female patients who were treated with chest radiation therapy for a childhood cancer. It was developed for use by health care providers. If you are not a healthcare provider, it is recommended that you discuss these results with your doctor. The calculator was designed to be used for adults who are survivors of a childhood cancer. It only calculates risks for patients who are at least 20 years old. Unfortunately, there is insufficient data to reliably predict breast cancer risk beyond the age of 60.
