Ultrasonographic Evaluation of Breast Cancer-related Lymphedema

The overall goal of this procedure is to diagnose breast cancer-related lymphedema and evaluate the therapeutic effect of resistive exercise by using ultrasonography to measure the thickness of subcutaneous tissue. Begin by laying the patient's arm in a supine position with both arms on the bed. Use a pen to mark the midpoint of the wrist crease, the midpoint of the medial and lateral epicondyles at the level of the elbow, in the bicipital groove.

Then connect these points using a ruler. Next, mark the first target area 10 centimeters proximal to the elbow point along the line between the elbow and bicipital groove. In the second target area, 10 centimeters distal to the elbow point along the line between the elbow and the wrist.
