What happened, in summary

Muriel was active, informed, and used to making decisions before breast cancer changed her life in May 2022, when she found a lump in her breast. Her care plan quickly expanded from mastectomy to discussions about chemotherapy and radiotherapy, but she did not want to hand over decisions about her body without understanding the tradeoffs. She read patient materials, spoke with other people affected by cancer, asked detailed questions, and sought several medical opinions. For surgery, Muriel chose a mastectomy with breast reconstruction using her own tissue instead of a silicone implant. She also looked for ways to avoid standard removal of lymph nodes in the left armpit, because preserving quality of life and lowering the risk of lymphedema mattered to her. When chemotherapy became the next major decision, she challenged the first recommendation after learning it could carry heart-related risks. A second oncologist proposed an equivalent but shorter option, which she chose. She stayed active through treatment and used a cooling cap to reduce the risk of permanent hair loss. As of 16 April 2026, Muriel was in antihormonal therapy, the final phase of treatment, living largely symptom-free and helping others as a peer counselor.
