The microwaves generated by the SWIFT machine excite the water molecules and cause friction. This friction heats up the skin cells to 42-45 C° which puts the virally infected cells of the wart into a state of stress.
The stressed cells release “danger signalling” heat shock proteins which induces maturation of Langerhans cells and enhances their migration to the lymph nodes.
Cytotoxic T cells migrate to the epidermis and begin to destroy all virally infected cells.
