ABSTRACT:
A method is provided for treating a tumor by pre-irradiation. The location, size, and shape of the tumor is identified. A region that includes the tumor as well as a surrounding portion most likely to contain residual tumorous cells is identified. The identified region is irradiated with therapeutic radiation, such as x-rays, prior to surgical removal of the tumor. The tumor is removed after irradiation of the identified region, leaving only the pre-irradiated surrounding portion. The risk of recurrence of tumorous growth after resection of the tumor may be significantly reduced.
