Brief summary: The purpose of this study is to determine whether hypnosis is efficacious in reducing musculoskeletal pain in breast cancer survivors taking aromatase inhibitors, and by doing so, whether hypnosis can help survivors to be more adherent to their medication regimen.

Detailed description: The primary purpose of this study is to evaluate the efficacy of hypnosis for reducing musculoskeletal pain (MSP) in women taking aromatase inhibitors (AIs) for breast cancer. Research indicates that AIs are associated with musculoskeletal pain in up to 61% of breast cancer survivors. AI-associated MSP can include joint pain in the wrists, hands, and knees; carpal tunnel syndrome and trigger finger; and decreased grip strength, morning stiffness, and general muscle pain. MSP can lead to difficulty performing daily activities and can reduce quality of life in breast cancer survivors. This pain is not only aversive in and of itself, but also is associated with non-adherence to prescribed, daily AI regimens. In some studies, AI non-adherence estimates were as high as 50%.

At the present time, there is no "gold standard" treatment for AI-associated MSP. What is needed is an intervention that: reduces breast cancer survivors' MSP and helps them be more adherent to their prescribed AI regimen, does not have side-effects of its own, does not place a large time or financial burden on survivors, and which can be taught to survivors to practice on their own.

Hypnosis, a mind-body intervention, has been widely demonstrated to reduce pain. In fact, analgesia is perhaps the best known effect of hypnosis. Meta-analyses have consistently supported the efficacy of hypnosis for pain control, including chronic pain. Hypnosis also has a long tradition in cancer symptom management, especially for pain reduction. Hypnosis has been defined as an agreement between a person designated as the hypnotist (e.g., health care professional) and a person designated as the client or patient to participate in a psychotherapeutic technique based on the hypnotist providing suggestions for changes in sensation, perception, cognition, affect, mood, or behavior.

This study will examine whether or not hypnosis is helpful in reducing breast cancer survivors' AI-related MSP and in improving their adherence to their prescribed AI regimen. This study will also examine whether the hypnosis intervention is cost effective. To answer these questions, this randomized clinical trial will compare hypnosis (three sessions) to a non-hypnosis, attention control, empathic listening condition (three sessions). For each intervention, the first session will be approximately 40 minutes, and sessions 2 and 3 will be approximately 30 minutes each. Both interventions will be delivered face-to-face, by a doctoral-level psychology professional.

All participants will be taking AIs for breast cancer, will be experiencing some musculoskeletal pain since starting AIs (≥3 on a 10 point scale), and will be randomized to one of the two intervention groups. Study participants will be asked to complete measures of pain, AI adherence, and other behavioral and psychosocial measures over the course of 12-month period. The follow-up assessments will evaluate the clinical efficacy and cost-effectiveness of hypnosis versus professional attention.

Overall, this project is a critical step towards reducing the struggles of breast cancer survivors experiencing AI-related MSP, and associated non-adherence. By reducing MSP and improving AI adherence, the hypnosis intervention tested here has the potential to improve quality of life and well-being.

Eligibility criteria: Inclusion Criteria:

* Female
* Diagnosed with Stage 0-III hormone-receptor positive breast cancer
* Taking a third-generation aromatase inhibitor (AI) (e.g., anastrozole (Arimidex), letrozole (Femara), or exemestane (Aromasin)) for at least 3 months left in their AI prescription to complete all study assessments (e.g., at least one year left on AIs)
* Experiencing ongoing pain and/or stiffness in one or more joints, which started or worsened after initiation of AI therapy
* Having a baseline worst pain score over the past week on the Brief Pain Inventory-Short Form (BPI-SF) of ≥ 3 on a 0 to 10 scale
* Over age 18
* Able to speak and read English (to allow for participation in study intervention sessions)
* Consent to the study
* Be willing to be randomized to experimental conditions
* Willing to travel to Mount Sinai for study procedures (e.g., intervention sessions, follow-up appointments).

Exclusion Criteria:

* Inflammatory, metabolic or neuropathic arthropathies at the time of recruitment
* Fibromyalgia
* Past cancer. Patients will be excluded if they have ever been diagnosed with cancer (including DCIS/LCIS) prior to the breast cancer for which the present course of AIs is being prescribed. However, patients will be eligible if they have a history of non-metastatic, non-melanomatous skin cancer
* Metastatic (Stage IV) breast cancer, as their treatment and outcomes typically follow a different course
* Bone fracture/surgery of an extremity during the preceding 6 months
* Non-steroidal joint injection within the last 3 months.
* Current use of corticosteroids, defined as oral, intravenous (IV), or injections of corticosteroids in the past 4 weeks
* Regular use of narcotics.
* Patients will be excluded due to the presence of the following psychiatric conditions: dementia, psychosis, current mania or uncontrolled major depressive disorder, or addictive disorder or current intoxication.
* In the rare instance of the presence of a comorbidity that does not fall into any of the above mentioned exclusion criteria, but that is clinically determined to significantly interfere with the patient's ability to participate in the study (e.g., cognitive impairment)
