Low dose regimens are used to decrease
the side effects of

the maximum therapeutic benefit.

You need to understand that the advantages of radiation therapy, hormone therapy and chemotherapy are prevention of recurrence, increasing the disease free survival period and to prevent the ocurrence of metastasis.
