Adenoid Cystic Carcinoma of the Breast

  • Adenoid cystic carcinoma of the breast:
    • Is a very rare subtype of breast cancer
    • It is usually triple negative
    • It is much less likely to have nodal involvement and is more common in postmenopausal women:
      • With a mean age of 66
    • Distant metastases are rare:
      • However, the lung is the most common site
  • It has a better prognosis than infiltrating ductal triple negative breast cancer:
    • With a 5-year overall survival rate of 88%.3
