• Conditions: Ductal Carcinoma in Situ; Stage I Breast Cancer; Stage II Breast Cancer; Stage III Breast Cancer

• Registration Number: NCT07095114
• Lead Sponsor: Barbara Ann Karmanos Cancer Institute

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Safety of Magic Ink	3 months after completion of Radiation Therapy	Number of participants with treatment related adverse events as assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE v5.0)

Secondary Outcome Measures

Name	Time	Method
Efficacy of Magic Ink	3 months after the completion of Radiation Therapy	Ease of radiation treatment (RT) setup. Participants will be categorized as "difficult" or "easy" setups. Difficult setups are setups with greater than 15% of the films for the treatment course result in a physician flag or reimaging based on clinically unacceptable or borderline acceptable setup.
Body Image Score	3 months after the completion of Radiation Therapy	Participants will complete a Body Image survey at baseline (prior to treatment) and 3 months after the completion of radiation therapy. The body image scale survey is a 10 question Likert scale where participants give a rating of Not at all, A little, Quite a bit or Very much. Responses will be compared to historical controls
