This document discusses risk factors, stages, and treatments for breast cancer. It summarizes that breast cancer has many risk factors, including breast density, genetics like BRCA1 mutations, and hormones like estrogen and IGF-2. The stages of breast cancer are used to determine the size of the tumor, metastasis to lymph nodes, and prognosis.
