They could be doing both. Similar to how oxidants stimulate cellular regeneration. If the THz waves induce mechanical destruction, especially on already weakened or damaged actin filaments, it could induce cellular repair mechanisms to create new action. It might be something useful in certain cases. Say, deep cellular regeneration... or not.
