Post-operative lymphedema treatment is different depending on the surgery, and different treatment methods are adopted. Currently, the safe and effective treatment method is manual drainage, and the specific operation differs according to the location: for example, breast cancer surgery mainly causes lymphedema in the upper extremities, so it is recommended to treat lymphedema in the upper extremities; gynecological cervical cancer and ovarian cancer cause lymphedema in the lower extremities, so it is recommended to perform manual drainage in the lower extremities; perineal edema is recommended to perform manual drainage in the perineum.
