Aromatase inhibitors (AIs) are commonly used in treating hormone-positive breast cancer. Unfortunately, many patients receiving this treatment experience Aromatase Inhibitor-Associated Musculoskeletal Syndrome (AIMSS), with symptoms like joint and bone pain and joint stiffness. The current therapies used to improve AIMSS symptoms have limited effectiveness and can cause their own side effects. In this research study, we are examining the feasibility of topical medical cannabis cream as a treatment option for AIMSS.
