This clinical trial evaluates how well tonation breathing techniques (use of a breathing and tonation [creating sounds]) works to ease pain joint and/or muscle pain in patients with stage I-III breast cancer and currently take an aromatase inhibitor. Tonation breathing techniques may help relieve pain in patients with stage I-III breast cancer who are receiving aromatase inhibitor.

PRIMARY OBJECTIVE:

I. To study impact of active participation of patients in producing tones in combination with breathing technique, i.e., tonation breathing techniques (TBT) to reduce aromatase inhibitor induced musculoskeletal symptoms.

OUTLINE:

Patients participate in tonation breathing techniques twice daily (or more if pain occurs) for 2 weeks. Patients also complete questionnaire at baseline and at 2 weeks.

Inclusion Criteria:

• Females with stage I-III breast cancer taking adjuvant aromatase inhibitor (AI) (either standard dose of anastrozole 1 mg daily or letrozole 2.5 mg daily or exemestane 25 mg daily) for greater than 30 days experiencing AI induced musculoskeletal pain scores of 5 or higher on a Likert scale will be enrolled
• Subjects should have completed any planned surgery for breast cancer, chemotherapy and radiation therapy at least 30 days prior to enrollment
• Patients should have an Eastern Cooperative Oncology Group (ECOG) performance score of 0-2
• Patients should be at least 18 years old with no maximum age limit

Exclusion Criteria:

• Patients should not have significant underlying pulmonary disease
