For the surgeon, especially when the tumor is on facial skin, removing the cancerous lesion constitutes a double challenge due to the need, on the one hand, to remove the entire tumor, and on the other hand, not to remove more healthy tissue than necessary. The concern is that removing tumor tissue with safety borders, which can reach several centimeters, will result in an unnecessary aesthetic damage.
Recently, the Tel Aviv Sourasky Medical Center has purchased a contact system, the most innovative and advanced in the world, designed for low energy radiation of skin lesions (up to 100 kilowatts). The system is equipped with a special high-resolution ultrasound imaging feature, determining the depth of the lesion, and facilitating the decision regarding the strength of the ray and the precise dimensions of the treatment area. The patient feels nothing during the treatment and it does not entail any anesthesia or sedation. The treatment takes place by holding the radiation device to the lesion area and no special preparations are necessary.
