The purpose of this pilot intervention study is to test the effectiveness of a self-management approach (combining education- and exercise-based strategies) for improving arthralgia (joint pain) associated with Aromatase Inhibitors (AI) in older breast cancer survivors. Survivors will be recruited from local cancer clinics prior to the completion of primary cancer treatment, as arthralgia can occur soon after initiating AI medication. Participants will be randomized to one of two groups: an enhanced standard care group (AI prescription plus information) or a treatment group (educational classes plus group exercise sessions). Older survivors (≥60 years) will be targeted because they are at increased risk of medication complications which may impede adherence. For the baseline assessment, a cancer-specific geriatric assessment will be conducted and a blood sample will be collected to interpret the effects of the self-management study in the context of geriatric experiences. Additionally, there will be an assessment of knowledge, PA habits, and AI-related joint pain and AI adherence. These will be measured again at 4, 6 and at follow up at 12 months.
