Neoplasia tumor is a medical term used to describe an abnormal growth of cells that can form a mass or lump. It is a type of cancer, and can be benign (non-cancerous) or malignant (cancerous). Neoplasia can start in any part of the body, and can be caused by a variety of factors, including genetic mutations, hormones, viruses, and environmental exposures.
Neoplasia tumors are typically classified according to the type of cell from which they originate. For example, squamous cell carcinoma arises from the cells of the outer layer of skin, while adenocarcinoma arises from the cells of the glandular tissue.
In order to diagnose and treat neoplasia tumors, doctors will typically perform a biopsy, in which a small sample of the tumor is taken for examination under a microscope. Depending on the type of tumor and the results of the biopsy, treatment may involve surgery, radiation, chemotherapy, or a combination of these methods.
