Breast
Whole breast, partial breast, post-mastectomy chest wall and regional nodes — setup, breath hold, target volumes, thoracic OARs and cited dose constraints.
Breast planning is a problem of a curved target on a moving chest wall. The breast or chest wall sits directly over the lung and, on the left, the heart, so most of the craft goes into covering a shallow, sloping target evenly while keeping the lung and heart out of the beams — often with the help of breath hold.
The same organs run through every approach — whole breast, partial breast, post-mastectomy chest wall and regional nodes — but the target, the schedule and the organ limits change between them. Each treatment page below has its own constraint table, quoted from a published protocol with the study behind every value.
Setup, breath hold, target volumes, boost and cited constraints for whole-breast treatment after breast-conserving surgery.
External-beam partial breast irradiation: tumor bed targets, uninvolved-breast sparing and ASTRO organ goals.
Chest wall treatment after mastectomy: scar wiring, bolus, reconstruction and cited constraints.
Breast or chest wall plus axillary, supraclavicular and internal mammary nodes: larger volumes, higher lung and heart dose, cited constraints.
