If a participant was diagnosed with prostate cancer during the trial, medical records of treatment for that cancer are obtained. Records were obtained only for treatments that occurred within one year of the cancer diagnosis, and include surgeries, radiation therapies and hormone therapies.

For most purposes, cancer treatment data can be obtained within the Prostate dataset. Additional details can be found in the Prostate Treatments dataset (one record per treatment per person).
