Brachytherapy is a form of radiation where the radiation source is placed very close to the skin cancer. This form of radiation can be applied to the tumor using metal applicators, a series of tubes, or a flap of beads that conforms to the skin (Freiburg flap). When high-dose-rate (HDR) treatments are given, treatments are usually scheduled two days per week instead of each day. Long-term studies following patients who have received brachytherapy show that this form of radiation is very effective in treating skin cancer and the vast majority continue to remain cancer-free many years after treatment. In general, the cosmetic outcome with HDR brachytherapy is excellent and recovery time is minimal.
