External beam radiotherapy - Wikipedia

With the easy-to-use 3D ceiling mount available in the treatment rooms, a variety of settings are possible. The treatment options are diverse, including plastic surgical excision, Moh’s microsurgery, electrocautery, topical 5-fluorouracil and imiquimod, photodynamic therapy and superficial radiotherapy.

Advances in surgical techniques have meant that the population of patients treated with radiotherapy has changed. energies available to a radiotherapy program. Low-energy X ray beams have application in the treatment of skin lesions and shallow tumors.
