Cellular Classification PDQ Treatment Summary for Health Professionals Written for physicians, this article talks about the various classifications of breast cancer tumors.
Lobular carcinoma involves both breasts more frequently than other histologic types.
Inflammatory carcinoma is a clinicopathologic entity characterized by diffuse brawny induration of the skin of the breast with an erysipeloid edge, usually without an underlying palpable mass. Radiologically there may be a detectable mass and characteristic thickening of the skin over the breast. This clinical presentation is due to tumor embolization of dermal lymphatics with engorgement of superficial capillaries. Inflammatory carcinoma is classified as T4d. Although most patients are cured with such treatment, the risk of developing local recurrence or metastases is related to infiltrating margins, degree of stromal mitotic activity, nuclear pleomorphism, and stromal overgrowth.
