High-grade DCIS. This designation refers to high-grade ductal carcinoma in situ. The adhesion molecules cd31 and cd44 are increasing expressed in very malignant breast ca. Such expression correlates well with tumor cells spreading within the ductal system of said breast.
High Grade DCIS. Ductal-carcinoma-in-situ (dcis) is a type of cancer where the cancer cells are confined within the milk ducts where they originate. This is often considered a "pre-cancer" due to the inability of these cancers to spread outside the breast. The grade of a cancer describes how rapidly the cells are dividing; the higher the grade, the higher the risk of invasive cancer if left untreated.
