The effective amount of radiation has been determined by many studies over many years. Whereas it's not possible to specify for each individual, it's known that for the groups of people studied, stopping the dose too soon will lead to a higher percentage of recurrances. So it's felt that it's very important to receive the full dose; and the boost. The boost doses you will receive will not hit the underarm and undersurface. The main thing is to be sure the radiation doctor, and not just the techs who give the doses, is aware of your skin situation. Sometimes a pause can be arranged. In rare cases, the dose is abbreviated.
