Does radiotherapy treat basal cell carcinoma?

Basal cell carcinoma is a skin cancer that can damage nearby tissue if it continues to grow, even though it usually spreads to distant sites less often than many other cancers. Surgery is often considered when the tumour can be removed safely, while radiotherapy uses targeted radiation to damage cancer cells in a planned area. Radiotherapy may be discussed for a tumour in a difficult location, when surgery is not suitable, after an incomplete removal, or when other factors affect the balance of benefit and harm. The plan depends on size, depth, location, previous treatment, and general health.

Obtain a confirmed diagnosis and discuss the pathology and treatment options with a dermatologist, surgeon, and radiation specialist as appropriate. Ask how the tumour borders will be defined, how nearby structures will be protected, how the skin may react during treatment, and what follow-up will involve. Do not delay review of a sore, crust, or pearly growth that changes or fails to heal. The Radiotherapy guide explains the treatment approach in more detail.

Arrange prompt assessment for a bleeding, crusting, enlarging, or non-healing skin lesion, especially near the eye, nose, ear, or lip. During or after radiotherapy, report severe skin breakdown, infection signs, persistent bleeding, or new symptoms affecting a nearby eye, ear, or mouth. Urgent care is appropriate for uncontrolled bleeding or rapidly worsening swelling.

Has the diagnosis been confirmed by pathology? Why is radiotherapy suitable for this tumour and how does it compare with surgery? What area will be treated and how long will the course take? Which short-term and delayed skin effects should I watch for? How will recurrence or a new skin cancer be checked?
