Which of the following is NOT a conservative measure for managing lymphedema?

Surgery is considered an invasive procedure and is not classified as a conservative measure for managing lymphedema. Conservative management typically focuses on non-invasive techniques aimed at reducing swelling and improving function in affected limbs. This includes the use of compression garments to prevent fluid accumulation, exercise to enhance lymphatic circulation and muscle pumping action, and the application of sequential massage units, which employ mechanical compression to promote lymphatic drainage. These methods aim to manage symptoms effectively without the need for surgical intervention, which is usually reserved for more severe cases or complications that do not respond to conservative therapies.
