After contouring the target volumes and organs at risk (OAR), standard whole breast rectangular field plans, 3D-CRT boost and electron boost plans will be generated. Dose prescribed would be 40 Gy/16#/3 weeks for whole breast rectangular plans and a boost of 10 Gy/5#/1week in arm A and 16Gy/8#/1.5weeks in Arm B. Plans will be evaluated both quantitatively (analyzing dose volume histograms) and qualitatively (by visually inspecting isodose curves). Plans will be inspected for conformity and doses delivered to target and organs at risk.
