Brachytherapy: radiation treatment applied directly to skin tumours

For certain skin tumours, treatment does not necessarily require surgical removal of the affected area. In carefully selected cases, radiation can be delivered very close to the tumour, minimising exposure to the surrounding tissues.

This method is called brachytherapy and involves the temporary placement of a radioactive source directly on the surface of the lesion or in its immediate vicinity. It is used primarily for certain forms of basal cell carcinoma and squamous cell carcinoma, when the size and depth of the tumour are suitable for this type of treatment. The method may also be considered in areas where surgery would be more difficult to perform or could affect the functionality or aesthetic appearance of the treated area.

Each treatment is tailored individually to the patient, ensuring that the radiation dose covers both the tumour and a safety margin around it. The choice of the appropriate method takes into account the type of tissue affected, the size and depth of the lesion, its location, and the individual characteristics of each patient.

People with suspicious or diagnosed skin lesions should discuss with their specialist whether this type of treatment is suitable for them.
