How is immunohistochemistry used in cancer diagnosis?
Immunohistochemistry (IHC) involves the use of antibodies to detect specific antigens in tissue sections. It is widely used in cancer diagnosis to identify the presence and localization of proteins within tumor tissues. IHC helps in determining the tumor type, grade, and stage, and it is essential for identifying molecular subtypes of cancer. This technique also plays a crucial role in guiding treatment decisions, particularly in the context of targeted therapies.
