Summary

This study looks at a way to help women under 40 with breast cancer keep their ability to have children after chemotherapy. Before starting chemo, participants receive hormone injections and tamoxifen to stimulate their ovaries, then eggs or embryos are frozen. The goal is to see if this process can be done without delaying cancer treatment.
