We recruited a patient sample of 123 women diagnosed with BC within the preceding 12 months (mean 4.9 months; SD 3.5) with stage 0‐III unilateral breast cancer. We identified 33% of potential participants from Stanford Cancer Center records, 26% from the Army of Women website, 26% from social media, and the remaining 15% from other sources. Among the BC patients, 61 had undergone or later underwent BMX, and the other 62 had undergone or later received non‐BMX treatments. The recruitment of 39 healthy controls was monitored to maintain comparability in demographics. The controls were women with no history of cancer, no first‐degree relatives or 2 or more second‐degree relatives with a BC diagnosis, or any first‐ or second‐degree relatives with ovarian cancer. We identified 57% of potential control participants from a Stanford University volunteer pool, 33% from the Army of Women website, and the remaining 10% from other sources. All women (BC and control) were English‐proficient, willing to suspend intake of benzodiazepines and to undergo brain MRI, and with no contraindications to MRI imaging (e.g., ferromagnetic metal in their body). Exclusion criteria included other current or past cancers, any significant neurologic disease, current untreated psychosis or bipolar disorder, substance/alcohol abuse/dependence, current use of psychotropic medication, pregnancy, and hearing impairment. The research protocol was reviewed and approved by the Stanford Institutional Review Board (protocol number: 34959), and all subjects provided written informed consent.
