This study is looking at whether respiratory muscle strength training can help prevent breathing muscle weakness in adults newly diagnosed with breast cancer who are preparing for surgery. Breast cancer treatments can sometimes weaken breathing muscles, making daily activities harder. Researchers want to see if this training, which involves using a handheld device for 15 minutes daily, can reduce this weakness. You would either receive respiratory muscle strength training or learn Guided Imagery Exercises (a relaxation technique using visualization). The study will compare these two approaches to see which is more helpful. You could join if you are an adult (18-100 years old) recently diagnosed with breast cancer, scheduled for surgery, and can speak English. You cannot join if you are pregnant or have certain other conditions.

Study design

This interventional study plans to enroll 40 participants. It compares two behavioral interventions: respiratory muscle strength training and guided imagery exercises.

What's involved

Participants will carry out exercises at home for at least 2 weeks. You will meet with a researcher at home for breathing measurements before starting exercises, after completing them, and again after surgery.

Compensation

Not stated in the trial record.

Follow-up

Your breathing will be measured at baseline, 2-4 weeks after starting exercises, and 2 weeks after surgery.
