What to Wear During Radiation Treatment for Breast Cancer

Radiation therapy for breast cancer requires protecting the highly sensitive skin in the treatment area. Daily clothing choices are important for managing skin reactions and maintaining comfort. Selecting the right garments minimizes friction, reduces irritation, and supports the healing process of the irradiated skin.

Maximizing Comfort and Skin Protection

The skin exposed to radiation becomes delicate and prone to irritation, making the choice of fabric for daily wear a primary concern. Loose-fitting clothing is necessary to prevent constant rubbing and chafing against the sensitive area, which can otherwise worsen radiation dermatitis. Tops should drape away from the chest and underarm, avoiding pressure points that could lead to skin breakdown.

The ideal materials are soft, natural fibers that allow for maximum air circulation and breathability. Fabrics like 100% cotton, bamboo, and silk are recommended because they are gentle and absorb moisture efficiently, keeping the treatment area cool and dry. This prevents the buildup of heat and sweat, which can exacerbate skin reactions.

Certain fabrics should be avoided due to their potential to irritate the compromised skin barrier. Heavy, coarse materials like wool or denim are abrasive, while synthetic fibers such as polyester or nylon trap heat and moisture. Inspect garments for construction elements that cause friction, including heavy seams, rough tags, or tight elastic bands that press directly onto the treated area.

Dressing for the Treatment Session

Choosing an outfit specifically for the treatment day ensures a smooth process at the clinic. A two-piece ensemble is advantageous, allowing access to the chest and torso without requiring the patient to completely disrobe. This maintains comfort and modesty while reducing changing time.

The top layer should be easily removable or adjustable to expose the treatment field for the radiation therapists. Loose-fitting button-down shirts, zip-up hoodies, or simple T-shirts that can be lifted up comfortably are ideal. Selecting tops without metal buttons, zippers, or embellishments near the chest area is important, as metal can interfere with the radiation beam.

Easy footwear, such as slip-on shoes or sandals, simplifies the process. While a gown is often provided for the treatment itself, wearing practical clothes to the clinic ensures comfort while waiting. Focusing on easy-to-manage clothing streamlines the daily routine, which often involves frequent visits over several weeks.

Avoiding Irritants and Friction

Beyond general fabric selection, specific items must be managed to prevent localized skin irritation. Traditional bras with underwires must be avoided, as the rigid metal and tight construction can dig into the irradiated skin and increase friction. Opt instead for a soft, non-wired camisole, a post-mastectomy bra, or a seamless, soft-cup sports bra that offers gentle support.

Jewelry worn near the treatment field must be removed before each appointment. This includes necklaces, earrings, and piercings in the chest or shoulder area, since metal can interact with the radiation beam and cause an increase in the skin dose, potentially leading to burns. It is safest to leave all valuables at home to avoid misplacing them.

Hidden irritants can also come from the way clothing is laundered, as chemical residue can transfer to the sensitive skin. Clothing worn next to the skin should be washed using only mild, unscented, and dye-free laundry detergent. Fabric softeners and dryer sheets should be avoided, as they leave a residue on the fabric that can trigger an inflammatory reaction on the fragile skin.
