A 49-year-old woman with metastatic breast cancer (ER+, PR-, HER2+, BRCA-) received targeted chemotherapy and a ketogenic diet for 26 months, then added a high-dose cannabinoid regimen (CBD and THC) and psilocybin-assisted psychotherapy. After five months, PET/CT scans showed no evidence of metastatic disease, and chemotherapy was stopped. A one-year follow-up CT found no residual or recurrent disease. Recurrence appeared at 18 months, when the cannabis dose had been reduced to 60% of the initial protocol; increasing it back to the original dose was followed by receding cancer progression over 16 months. The case suggests potential therapeutic utility of adjunctive cannabinoids and psychedelics in metastatic breast cancer.
