You may have radiation after Surgery to kill cancer cells that might have been left behind.
It is also prescribed as the only treatment for disabled people or others who have health problems that make it unsafe for them to undergo Surgery. Radiation also can be used instead of Surgery if the tumour is massive or in a hard-to-treat region (like the eyelids or the tip of your nose) and the procedure may influence how you appear.
Yet non-melanoma skin cancers treated only with radiation are more likely to come back than those treated with Surgery. And if you have specific other health problems, such as lupus or scleroderma, Radiotherapy can sometimes make those outcomes worse.
