Overexpression and amplification of the neu (c-erbB2, ERBB2) protooncogene have been implicated in the development of aggressive human breast cancer. Our old friend the papillopma, i.e., a fingerlike proliferation of epithelium, growing over a fibrovascular core. Severe damage to the mammary gland associated with mastitis (bacterial or viral) or trauma may result in fibrosis of the secretory tissue and the loss of function in one or both halves of the mammary gland.

Another risk factor for the development of dyshormonal changes in the mammary glands is iodine deficiency, which contributes to disorders in the hypothalamus-breast system. Because of its prognostic role as well as its ability to predict response to trastuzumab , breast tumors are routinely checked for overexpression of HER2/neu. 4. The clinical appearance is usually a demarcated, thickened, eczematoid, erythematous weeping or crusted lesion with irregular borders. Note the myoepithelial cell. The tumor cells are INSIDE the skin dermal lymphatic spaces. Disease of the breast may prevent you from completing this task and cause serious harm to the health of the woman. Predominant glandular component – adenas. Regulated by the endocrine system, mammary glands respond to the hormonal changes that take place during pregnancy and following birth.The mammary glands are responsible for lactation, also known as milk production. The mammary gland is a skin gland, and is external to the body cavity. The mucinous variant is also somewhat better in behavior.
