Breast cancer types

Breast cancer types, with relative incidences and prognoses.
Cancer type Histopathology Image
Invasive ductal carcinoma (IDC) Carcinomatous cells are seen below the basement membrane of lactiferous ducts. Otherwise, there are no specific histologic characteristics, essentially making it a diagnosis of exclusion.[1] Histopathology of invasive ductal carcinoma of the breast.jpg
Ductal carcinoma in situ (DCIS) Malignant epithelial cells confined to the ductal system of the breast, without invasion through the basement membrane.[2] DCIS - Intraductal carcinoma of the breast.jpg
Invasive lobular carcinoma (ILC) The "classic" pattern is round or ovoid cells with little cytoplasm in a single-file infiltrating pattern, sometimes concentrically giving a targetoid pattern. Classic Invasive Lobular Carcinoma of the Breast (6813147194).jpg
Lobular carcinoma in situ (LCIS)
  • Monomorphic, loosely cohesive, slightly enlarged and evenly spaced cells that fill acini.[3]

Cells have indistinct cell borders, pale cytoplasm, and uniform small nuclei with evenly distributed chromatin and inconspicuous nucleoli.[3]

Mucinous carcinoma Extracellular mucin areas around tumor cells. Histopathology of mucinous invasive ductal carcinoma of the breast.jpg
Medullary carcinoma Seemingly fused tumor cells (syncytial pattern), and a prominent lymphoid infiltrate. Histopathology of medullary breast carcinoma.jpg
Solid papillary carcinoma Larger tumor nests with fibrovascular cores. Histopathology of solid papillary carcinoma.jpg
