The majority of breast carcinomas are of the ductal type, followed by lobular carcinoma. These two types together account for more than 70% of carcinomas. Although some rarer histological types are associated with distinct biological behavior and, consequently, require a special therapeutic approach, other morphological characteristics should be added to the typing to improve characterization of the evolution, such as histological grading (AGUILLAR, 2009). Regarding this type of pathology, choose the INCORRECT alternative:

A The medullary, classic lobular, and invasive papillary carcinomas have an intermediate prognosis compared to ductal carcinoma, which is similar to non-classic lobular carcinomas.
B Among the special histological types, some have a more favorable biological behavior compared to ductal carcinoma, such as tubular carcinomas.
C Others have a more aggressive behavior, such as metaplastic and invasive micropapillary carcinomas.
D Medullary carcinoma manifests as proliferation in one or more terminal ducts or acini of a loosely adhered cell population.
