Summary
Brief summary (as posted)
The goal of this clinical trial is to learn if respiratory muscle strength training can prevent respiratory muscle weakness in adults who are newly diagnosed with breast cancer and are planning to have surgery. The main question it aims to answer is: * Does respiratory muscle strength training in adults preparing for breast cancer surgery reduce the weakness that often occurs with surgery. Researchers will compare Guided Imagery exercises to respiratory muscle strength training to see which is more helpful. Participants will: * Carry out respiratory muscle strength training or Guided Imagery exercises for at least 2 weeks at home. * Meet with the researcher at home to complete breathing measurements before starting the exercises, after completing the exercises, and again after surgery. * Keep a diary of the exercises that have been completed.

- EXPERIMENTAL
- label
- Respiratory muscle strength training
- description
- Participants assigned to this arm will receive the equipment, education, and training to be able to perform respiratory muscle strength training for at least two weeks before breast cancer surgery.

- Behavioral: Respiratory muscle strength training
- type
- ACTIVE_COMPARATOR
- label
- Guided Imagery Exercises
- description
- Participants assigned to this group will receive education and training to be able to perform Guided Imagery, an exercise that uses relaxing, calming mental images, for at least two weeks prior to breast cancer surgery. This exercise does not provide respiratory strengthening and will thus be used as a comparator to respiratory muscle strength training.
