What happened, in summary

Kate Watson was 35, with 2 young daughters, when she learned she had Stage IV HER2-positive metastatic breast cancer. The cancer had already spread beyond the breast to lymph nodes in her chest and to spots in her spine, pelvis and one femur. The diagnosis was especially shocking because she had no breast cancer family history, exercised, never smoked and was younger than routine mammography screening age. Kate began intensive chemotherapy immediately after diagnosis and continued those cycles for 3 months. Her cancer was HER2-positive, a subtype that can respond strongly to HER2-targeted treatment. After chemotherapy, her care shifted to ongoing monthly maintenance therapy through an IV port in her chest. That maintenance combination included trastuzumab (Herceptin), pertuzumab (Perjeta) and other medicines. She did not have surgery. The treatment produced a complete response and regular PET scans later showed no evidence of active disease. As of October 2019, Kate had been in remission for about 3 years while still receiving monthly maintenance therapy. She also became an advocate for metastatic breast cancer research, raising funds and awareness because HER2-targeted drugs had made her long-term survival possible.
