Both breasts are affected in which type of breast carcinoma: September 2009
Ans. D: Lobular Carcinoma of the breast is a histologically heterogeneous disease. Invasive lobular carcinoma (ILC) accounts for 8-14% of all breast cancers. The morphologic features of lobular carcinoma differ from those of ductal carcinoma. ILC is characterized by small, round cells that are bland in appearance and have scant cytoplasm, which infiltrate the stroma in single file and surround benign breast tissues in a targeted manner. Infiltration typically does not destroy anatomic structures or incite a substantial connective tissue response. By viue of their distinctive growth pattern and biology, lobular carcinomas often fail to form distinct masses that can easily be diagnosed by palpation or mammography. This can make early diagnosis challenging and breast conservation approaches more difficult. Lobular carcinomas may have a substantially increased propensity for multifocal and multicentric distribution and for bilaterality.
