What are effective remedies for skin breakdown in the axilla after radiotherapy?

Radiotherapy is a cancer treatment whose efficacy depends on radiosensitivity—the degree to which different tissues, organs, and tumor types respond to radiation exposure varies significantly. Radiosensitivity is associated with the proliferative cycle of tumor cells and their histopathological grade: rapidly proliferating cells are more radiosensitive than non-proliferating ones, and higher cellular differentiation correlates with lower radiosensitivity (and vice versa, lower differentiation implies higher radiosensitivity). So, what can be done if skin breakdown occurs in the axilla following radiotherapy? Below, we address this question.

Management Options for Axillary Skin Breakdown After Radiotherapy

There is no definitive or universally effective treatment specifically for axillary skin breakdown after radiotherapy; however, symptom relief can be achieved through topical medication application.

Radiotherapy is a standard cancer treatment that uses ionizing radiation to target and destroy malignant cells. Following irradiation, tumor growth typically slows or halts, and further metastasis may be inhibited. However, patients with compromised immunity are particularly prone to radiation-induced skin injury—including skin breakdown—especially in delicate, thin-skinned areas such as the axilla. Prompt intervention is essential to prevent secondary infection.

Topical application of medications such as boric acid ointment or mupirocin ointment may help manage the condition. Mupirocin ointment possesses anti-inflammatory and analgesic properties, while boric acid ointment helps prevent local infection. In addition, daily topical disinfection with povidone-iodine followed by appropriate sterile dressing is recommended.

Patients should maintain meticulous local hygiene and avoid spicy foods and seafood during recovery.
