Description

A mucinous neoplasm (also called colloid neoplasm) is an abnormal and excessive growth of tissue (neoplasia) with associated mucin (a fluid that sometimes resembles thyroid colloid). It arises from epithelial cells that line certain internal organs and skin, and produce mucin (the main component of mucus). A malignant mucinous neoplasm is called a mucinous carcinoma. For example, for ovarian mucinous tumors, approximately 75% are benign, 10% are borderline and 15% are malignant. When found within the skin, mucinous carcinoma is commonly a round, elevated, reddish, and sometimes ulcerated mass, usually located on the head and neck.

The classification of breast cancer places the disease into distinct categories based on various criteria and serves distinct purposes. The most important categories are the tumor's histopathological type, grade, stage, and expression of proteins and genes. These classifications are updated as new information about cancer cell biology becomes available. The best treatment is chosen through classification. Typically, randomized, controlled trials are used to demonstrate the efficacy of a particular treatment for a particular type of breast cancer. It's possible that this treatment won't work for another type of breast cancer. Some breast cancers are aggressive and pose a life-threatening threat, necessitating aggressive treatment with significant side effects. Other bosom diseases are less forceful and can be treated with less forceful medicines, like lumpectomy. The classification of breast cancer is used by treatment algorithms to identify specific subgroups that are each treated based on the best available evidence. Characterization perspectives should be painstakingly tried and approved, with the end goal that puzzling impacts are limited, making them either obvious prognostic elements, which gauge sickness results, for example, illness free or generally endurance without a trace of treatment, or genuine prescient variables, which gauge the probability of reaction or absence of reaction to a particular therapy. The histological appearance of the tissue in the tumor is typically, but not always, the primary factor used to classify breast cancer. Inflammatory Breast Cancer (IBC), a type of ductal carcinoma or malignant cancer in the ducts, is distinguished from other carcinomas by the inflamed appearance of the affected breast, which correlates with increased cancer aggressivity. This variant of this approach is defined based on the findings of a physical exam. Different schemata can be used to classify breast cancers. Treatment response and prognosis are influenced by each of these factors. The best way to describe a breast cancer is to include all of these classification aspects as well as other findings, like physical exam signs. Histopathological type, grade, stage (TNM), receptor status, and the presence or absence of genes as determined by DNA testing are all included in a complete classification.

Because it determines whether targeted treatments like tamoxifen and or trastuzumab are appropriate, receptor status is an essential assessment for all kinds of breast cancer. Some of the most effective adjuvant breast cancer treatments are now these ones. Estrogen Receptor Positive (ER+) cancer cells are dependent on estrogen for growth. As a result, they can be treated with drugs that reduce either the effect of estrogen (like tamoxifen) or the actual level of estrogen (like aromatase inhibitors) and, as a result, generally have a better prognosis. In general, HER+ patients had a worse prognosis before modern treatments, but HER2+ cancer cells respond to drugs like the monoclonal antibody trastuzumab when used in conjunction with conventional chemotherapy, which has significantly improved the prognosis. On the other hand, in the absence of targeted treatments, triple negative cancer, or cancer with no positive receptors, currently has a relatively poor prognosis. 80-90% of ER+ breast cancers and 40% of "triple negative" breast cancers express androgen receptor. In ER+ breast cancer, activation of androgen receptors appears to promote growth while suppressing growth in ER- breast cancer. This is being used as a marker for prognosis and treatment.
