Risk/benefit balance for the different techniques for all groups (Group 1: left-sided under DIBH, Group 2: left-sided in FB, Group 3: left-sided in FB with the lumpectomy cavity only located in the lower inner quadrant and Group 4: right-sided in FB). The horizontal dotted lines indicate the estimated mortality reduction due to radiotherapy for patients with different tumor aggressiveness; the columns show the estimated increased mortality risk from lung cancer, ischemic heart disease and contralateral breast cancer due to radiotherapy.
