The SRT-100 treats keloids and non-melanoma skin cancers that are found on the surface of the skin. It can be used for lesions on the arms, back and trunk, but it is especially well suited for skin cancers of the head and neck regions. This treatment avoids the anxiety of surgery. Halting anti-coagulators is not necessary. SRT is also great treatment option for patients who are considered high risk for surgical procedures.
