What Role Do Immunohistochemistry and Molecular Tests Play?
Immunohistochemistry (IHC) and molecular tests are complementary to traditional histological techniques. IHC involves using antibodies to detect specific proteins in cancer cells, such as estrogen receptors (ER), progesterone receptors (PR), and HER2. These markers can provide important information about the cancer's behavior and potential response to targeted therapies. Molecular tests can identify genetic mutations and alterations that may also influence treatment options.
