When Is Radiotherapy Recommended for Basal Cell Carcinoma?

Basal cell carcinoma is often managed with a procedure that removes the tumour, but the choice depends on its size, depth, position, edges, growth pattern, and the person’s general health. Radiotherapy uses focused radiation to damage cancer cells in a planned area. It may be discussed for a tumour near a structure where surgery could affect function, for someone who cannot have surgery, or when further surgery is not suitable.

The treatment plan can involve several appointments, with the schedule set by the radiation oncology team. Skin in the treated field can become red, dry, tender, or temporarily changed. Your team will explain likely effects for the exact site.

Ask your dermatologist to explain the biopsy result, tumour boundaries, and available treatments. A multidisciplinary discussion may compare surgery, radiotherapy, and other approaches according to the tumour’s location and your priorities. Share implanted devices, prior radiation, medicines, healing problems, and other health conditions before planning.

Keep the area protected from sun and attend every planned review. Follow written skin-care instructions during radiotherapy, and avoid applying unapproved products to the treatment field.

Arrange prompt assessment for a sore, scab, or bleeding area that does not heal, especially if it enlarges or returns after treatment. During or after radiotherapy, contact the treatment team for severe skin breakdown, worsening pain, fever, drainage, or symptoms affecting nearby structures.

Ask why radiotherapy is being considered, how the treatment field will be chosen, what alternatives are realistic, how nearby eyes, nose, ears, or nerves will be protected, and how follow-up will check the area.
