While in general terms, a great majority of cancerous
tissues decrease their proliferation due to apoptosis caused by radio — and chemotherapeutical regimes, most of them acquire novel mutations bypassing apoptosis to find novel niches to metastasize.
A continuous mode maximizes thermal effects; this mode is therefore primarily used for
tissue heating before stretching.9 Pulsed modes produce
decreased thermal effects but are used for other applications, including acceleration of the inflammatory process, increased fibroblast
proliferation, and increasing the tensile strength of healing
tissues.9
