Lymphedema is a persistent and chronic swelling condition that commonly develops after breast cancer surgeries involving axillary lymph node dissection (ALND). This condition causes pain, heaviness, and swelling in the upper limb, which severely limits shoulder mobility and functional performance in daily life tasks. While manual lymphatic drainage (MLD) is widely utilized to stimulate lymphatic flow and reduce tissue swelling, the added therapeutic benefit of combining it with deep breathing exercises remains less evaluated. This study is a randomized controlled trial designed to investigate whether combining diaphragmatic breathing exercises with manual lymphatic drainage is more effective than manual lymphatic drainage alone. The main goals of this study are to determine if this combined intervention provides greater reductions in arm circumference and subjective pain levels while significantly improving upper extremity range of motion and overall functional ability in female patients recovering from a radical mastectomy.

Participants who meet the eligibility criteria will be recruited from the University of Lahore Teaching Hospital and affiliated clinical settings. Following informed consent, participants will be randomly assigned to one of two parallel groups using the lottery method to ensure unbiased allocation. The total study duration will span 4 weeks, with clinical outcomes measured at baseline and at the conclusion of the 4th week. Both groups will first receive a standardized baseline physical therapy program consisting of: 1. Transcutaneous Electrical Nerve Stimulation (TENS) applied for 10 minutes. 2. Active range of motion (AROM) exercises for the shoulder, elbow, and wrist (10 repetitions each). 3. Gentle upper limb muscle stretching (3-5 repetitions with a 10-second hold). Following the baseline session, the groups will receive their distinct experimental protocols: * Group A (Control Group): Will receive 25 to 30 minutes of specialized Manual Lymphatic Drainage (MLD). This manual therapy will employ gentle, slow, and rhythmic skin-stretching strokes directed toward functioning, proximal, unaffected lymph nodes to enhance fluid clearance. * Group B (Experimental Group): Will receive the identical 25 to 30 minutes of MLD, followed immediately by 2 minutes of structured diaphragmatic breathing exercises. Participants will practice controlled deep breathing in a comfortable, semi-reclined position (inhaling through the nose for 4 seconds, allowing the abdomen to rise, followed by exhalation and a 4-second pause before the next breath). The entire intervention protocol will be conducted 3 times a week for a duration of 4 weeks. Standardized outcome evaluations will monitor changes in limb circumference discrepancy via tape measurements, upper limb functional mobility using a universal goniometer, disability levels using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and subjective pain levels on the Numeric Pain Rating Scale (NPRS).
