Abstract

Radiotherapy is an integral part of treatment of breast cancer. It improves disease control and lowers the rate of local recurrence. It is also used as salvage therapy. There are draw backs of breast radiation therapy, both short term and long term. This is mainly due to the irradiation of organs at risk. The dose to the organs at risk more often than not influences the treatment planning. We always aim to attain an equilibrium where we give adequate dose to the target while minimizing the dose to the organs at risk as much as possible. One of the ways of achieving this balance has notably been with the use of newer technology. This has led to the comparisons between these different techniques.
Aim of the study: The aim of this study was to make a dosimetric comparison between conventional 3DCRT tangential radiotherapy with virtual wedges (wedge) and field-in-field forward planned IMRT (FiF) in patients undergoing whole breast radiotherapy.
