This prospective prehabilitation trial evaluated the effectiveness of an individualized exercise program initiated before breast cancer surgery and maintained for 12 months. The intervention aimed to promote functional recovery and improve patient-reported outcomes.

Women scheduled for breast surgery due to breast cancer were enrolled in an individualized prehabilitation program that began in the preoperative period and continued for 12 months. The exercise program included range-of-motion, strengthening, and postural correction exercises delivered through supervised and home-based sessions. Outcomes were evaluated at baseline and at 1st, 3rd, 6th, and 12th months. Functional outcomes, shoulder range of motion, pain intensity, lymphedema development, and patient-reported quality of life were assessed.

• Female patients diagnosed with breast cancer scheduled for surgical treatment
• Age ≥ 18 years
• Able to perform exercise
• Provided informed consent

Exclusion Criteria:
