Which action reduces the risk of skin injury during radiation therapy?

Wearing loose clothing over the affected area is the action that significantly reduces the risk of skin injury during radiation therapy. Loose clothing minimizes friction and irritation against the skin, which is essential because the skin can become sensitive and fragile as a result of exposure to radiation. When the skin is already compromised, as it often is during radiation treatment, tight clothing can lead to further damage, irritation, or even painful skin reactions.

In contrast, using hot compresses can exacerbate skin irritation and may complicate the healing process by increasing blood flow and potentially leading to burns or further damage. Applying creams not prescribed by the provider can introduce irritants or allergens that could worsen skin conditions or interactions with radiation effects. Lastly, rubbing the treatment area can also damage sensitive skin and create more irritation or open wounds, which can increase infection risk or delay healing. Thus, wearing loose clothing stands out as the best practice to protect skin integrity during radiation therapy.
