Patients who are eligible to receive adjuvant whole breast radiotherapy with or without regional nodal irradiation as part of their care will be included in this study. Patients will use Silver-plated technology (SPT) dressing as directed per user instruction manual and change dressings weekly. Patients will continue to wear the SPT dressing for 2 weeks following completion of RT. The presence and severity of ARD will be recorded at the time of the weekly OTV and at one month after finishing the treatment.

Adjuvant radiotherapy for breast cancer is standard in the setting of breast conserving therapy. The most common acute toxicity in those receiving breast radiotherapy is acute radiation dermatitis (ARD). This is not only disfiguring, but also painful and uncomfortable. No standard exists for the mitigation or treatment of ARD. Routinely, emollients and steroid based creams, including but not limited to, xeroform gauze, demeboro soaks, triple antibiotic cream, Silvadene, hydrocortisone, and mometasone creams are used. Steroid creams have been shown to change the skin microenvironment and also thin the skin - this is especially concerning as one of the primary goals of BCT is good to excellent cosmetic outcome. Mepitel dressings have been evaluated but are often cumbersome to use and difficult to apply accurately. Silver-plated technology (SPT) dressing, a novel skin dressing, has been shown to have anti-microbial effects thereby reducing the development of ARD. This prospective single arm phase II study will evaluate if SPT dressing reduces the incidence of grade 2 or higher ARD in breast cancer patients who are going to receive adjuvant radiotherapy.

Inclusion Criteria:

4. Agreeable to use of SPT dressing as directed (changing once weekly during RT and the additional 2 weeks following completion of RT).
5. Agreeable that any normal or physician recommended skin care regimen is to be used 1 hour prior to use of SPT dressing.
