Adjuvant Radiation Therapy For Invasive Breast Cancer

This is a clinical practice guideline for adult patients with invasive breast cancer who have had breast conserving surgery (BCS) or a mastectomy. The guideline reviews radiotherapy treatment according to lymph node status (positive or negative). Additionally, recommendations are provided for radiotherapy treatment with neoadjuvant chemotherapy, and the guideline discusses the risk of cardiac dose for patients with left-sided breast cancer and how this risk might be minimized.
