Brief Summary

The goal of this clinical trial is to test whether psilocybin along with therapy in women with early breast cancer and ovarian cancer in remission can improve their fear of recurrence. The main question\[s\] it aims to answer \[is/are\]: Does psilocybin assisted therapy improve fear of cancer recurrence? Does psilocybin assisted therapy improve anxiety, depression, and quality of life? Participants will complete a series of survey measures, participate in preparatory therapy. After prep therapy is complete, they will receive a moderately high dose of psilocybin in a monitored and supportive environment. After the dosing day, they will complete 4 sessions of integrative therapy and complete survey measures.
