Answer

Tubular carcinoma of the breast is an uncommon histologic type, accounting for only 1-2% of all breast cancers. Characteristic features of this type include a single layer of epithelial cells with low-grade nuclei and apical cytoplasmic snoutings arranged in well-formed tubules and glands.

Tubular components make up more than 90% of pure tubular carcinomas and at least 75% of mixed tubular carcinomas. This type of breast cancer has a low incidence of lymph node involvement and a very high overall survival rate. Because of its favorable prognosis, patients are often treated with only breast-conserving surgery and local radiation therapy.
