Simple: Most fibroadenomas are the simple type; they are more common in younger people.There's usually just one mass in your breast, with a definite border and very uniform cells. This model affords the opportunity for investigators to study the process of mammary carcinogenesis over a very short latency and to investigate early events in this process.

Aims: Breast myxoid fibroadenomas (MFAs) are characterized by a distinctive hypocellular myxoid stroma, and occur sporadically or in the context of Carney complex, an inheritable condition caused by PRKAR1A-inactivating germline mutations. Background: To determine the cytomorphological features of complex type fibroadenoma (CFA), we reviewed fine needle aspiration (FNA) cytology with correlation to its histopathology findings, and compared them with non-complex type fibroadenoma (NCFA). "Radiologic evaluation of breast disorders related to pregnancy and lactation.". A simple fibroadenoma does not raise your risk for breast cancer. When histopathology on core biopsy reveals a higher-risk lesion, such as atypical lobular hyperplasia, excisional biopsy may be indicated to rule out malignancy.

No calcifications are evident. "Cellular" is something that can be subjective. Small capillary-like structures in the stroma. The pathology is in the stroma; so, the lesion is really a misnomer by the naming rules. Epithelial component often not compressed - as in fibroadenoma.
