NEOPLASM ANTIGENS Meaning and
Definition
-
Neoplasm antigens refer to the molecules or substances that are specifically expressed or produced by neoplastic (cancerous) cells. These antigens serve as markers or signals that distinguish cancer cells from normal, healthy cells.
Neoplasms, or tumors, are characterized by uncontrolled and abnormal cell growth. As these cells multiply and form a mass, they may exhibit changes in their behavior and molecular composition. Neoplasm antigens arise from these alterations and can vary in their expression patterns among different types and stages of cancer.
Neoplasm antigens can be classified into several categories based on their origin and function. Tumor-specific antigens (TSAs) are unique to cancer cells and not found on normal cells. These antigens are the most ideal targets for cancer immunotherapy and diagnostics, as they provide the highest specificity for cancer cells. Tumor-associated antigens (TAAs) are also expressed by normal cells but are overexpressed or altered in cancer cells. These antigens can serve as targets for immune system recognition and are commonly used in cancer vaccines and targeted therapies.
The identification and characterization of neoplasm antigens play a crucial role in cancer diagnosis, prognosis, and treatment. They can be detected in various bodily fluids, including blood and urine, and are often assessed using laboratory techniques such as immunohistochemistry and molecular profiling. By targeting neoplasm antigens, researchers and clinicians aim to develop personalized therapies that selectively eliminate cancer cells while minimizing damage to healthy tissues.

Etymology of NEOPLASM ANTIGENS
The etymology of the word "Neoplasm" and "Antigens" can be explained as follows:
1. Neoplasm: The word "neoplasm" is derived from the Greek words "neo-", meaning new or abnormal, and "-plasma", meaning growth or form. "Neo-" in this context refers to the abnormal growth or formation of new tissue that characterizes tumors or cancers.
2. Antigens: The term "antigen" is a combination of two words: "anti-", which means against or opposite, and "gen", which comes from the Greek word "genein", meaning to produce or generate. In the context of immunology, an antigen refers to a substance or molecule that can stimulate an immune response or reaction.
