Surgery and radiation therapy, along with adjuvant hormone or chemotherapy when indicated, are considered primary treatment. Surgical therapy may consist of lumpectomy or total mastectomy. Radiation therapy may follow surgery in an effort to eradicate residual disease while reducing recurrence rates. There are 2 general approaches for delivering radiation therapy:

  • External-beam radiotherapy (EBRT)
  • Partial-breast irradiation (PBI)

Surgical resection with or without radiation is the standard treatment for ductal carcinoma in situ.
