Document Summary

For patients who will not receive nodal irradiation. Effect on cardiac dose varies depending on anatomy. Supine position with both arms above the head. Mastectomy scar, drain sites, and clinical boundaries of breast tissue: marked with radiopaque wire. Contralateral breast can be used to determine the appropriate location of the inferior, lateral and superior borders. Desired target in the breast conservation setting is the entire ipsilateral breast. Care must be taken to ensure adequate coverage. Nodal irradiation in the setting of four/+ involved axillary ln. Showed axillary dissection in controlling the axilla in the setting of positive sentinel ln biopsy after breast conservation: with a significantly lower rate of lymphedema. Increasingly common to consider regional nodal rt rather than axillary dissection. Patient is placed in the supine position with arms up on: a breast board, vac-lok, or, other immobilization device. A tilt should be applied to the immobilization device. In order to isolate breast tissue below the clavicle.
