Brief Summary: The purpose of this study is to determine whether starting anastrozole prior to radiotherapy so that it is taken during radiotherapy decreases local recurrence of breast cancer in post-menopausal women in comparison to waiting until after radiotherapy to commence anastrozole
Detailed Description: Adjuvant radiotherapy is well established as the primary modality to enhance local control in breast cancer The use of adjuvant hormone therapy such as tamoxifen has shown to improve local control to a relatively minor amount on its own and does enhance local control of adjuvant radiotherapy There is however conflicting invitro and clinical data regarding the effects or different sequences on tamoxifen and radiotherapy in terms of both local control and enhancement of radiotherapy toxicities

Aromatase inhibitors such as anastrozole are establishing themselves as a class of drug superior to tamoxifen for the control of estrogen dependent breast cancers and overall are better tolerated with the exception of greater bone loss

As the key question is whether the sequencing of the aromatase inhibitor anastrozole alters local control by acting as an enhancer of the radiation breast cancer cell kill it is therefore the aim of this study to compare 3 months of anastrozole prior to radiotherapy versus 3 months of anastrozole after radiotherapy with a specific objective of reducing the baseline ratio of in-field radiotherapy failure from 6 to 3
