About

The goal of this clinical trial is to learn if tattoos applied with Magic Ink is as safe as commercially available standard tattoo ink for the purpose of radiation in women with breast cancer undergoing radiation treatment. The main questions are:

• Is the Magic Ink as safe as standard tattoo ink
• Does Magic Ink continue to function and remain visible for radiation therapists during the treatment Participants will be consented and given a skin assessment. Once enrolled participants will be administered the Magic Ink tattoo instead of the standard tattoo ink in preparation for their radiation treatment. Participants will also complete a survey regarding body image. Skin assessment will occur again after the first week of radiation and at 3 months later. Throughout the radiation therapy the medical physicist will complete surveys about ease of set-up of the equipment.
