What does vascular invasion mean? Vascular invasion (also known as angioinvasion) describes the movement of tumour cells into a blood vessel such as a capillary, artery, or vein. Vascular invasion is almost always associated with malignant (cancerous) tumours although some benign (non-cancerous) tumours can also (very rarely) show vascular invasion. Vascular invasion is important because …

What is a well differentiated neuroendocrine tumour? A well differentiated neuroendocrine tumour (NET) is a type of cancer made up of specialized neuroendocrine cells. The tumour is described as “well differentiated” because the cells in the tumour look very similar to normal, healthy neuroendocrine cells. These tumours can be found almost anywhere in the body. …

What is a neuroendocrine carcinoma? Neuroendocrine carcinoma (NEC) is a type of cancer made up of specialized neuroendocrine cells. Neuroendocrine carcinoma can be found almost anywhere in the body. Other names for this type of cancer are poorly differentiated neuroendocrine carcinoma and poorly differentiated neuroendocrine neoplasm (NEN). What are neuroendocrine cells? Neuroendocrine cells are a …

What does nuclear atypia mean? In pathology, nuclear atypia is used to describe nuclei that are abnormal in size, shape, or colour when examined under the microscope. The nucleus (the term nuclei is used to describe more than one) is the part of the cell that holds the genetic material or DNA. A group of …

What is low grade dysplasia? Low grade dysplasia is an abnormal pattern of growth that can turn into cancer over time. This change is described as “low grade” because the abnormal cells look like normal, healthy cells when examined under the microscope. Does low grade dysplasia mean cancer? Low grade dysplasia does not mean cancer …

What does high grade dysplasia mean? High grade dysplasia is an abnormal pattern of growth that can turn into cancer over time. This change is described as “high grade” because the cells look very abnormal when examined under the microscope. Does high grade dysplasia mean cancer? High grade dysplasia does not mean cancer but if …

What does low grade mean? In pathology, low grade is used to describe cells that look abnormal when examined under the microscope but still share some features with normal, healthy cells. In order to determine if cells are low grade, pathologists often compare the abnormal-looking cells to the cells normally found in that part of …
