What is Immunohistochemistry (IHC) and its significance in cancer diagnosis?
Immunohistochemistry (IHC) is a technique used to visualize the expression and localization of specific proteins in tissue samples using antibodies. In cancer diagnosis, IHC helps in identifying the presence of tumor markers, understanding the tumor microenvironment, and classifying different types of cancers. It is particularly valuable in determining the origin of metastatic tumors and guiding treatment decisions.
