The new cells function as the original cells (called differentiation), when a benign tumor occurs and is the result of a genetic mutation in the benign tumor. Benign tumors usually cannot turn malignant, except in cases such as colon polyps.

Today, immunohistochemistry has become a modern, very effective and indispensable method for the pathologist in the differential diagnosis of malignant - benign tumors, not only stopping at diagnosis but also very effective for the prognosis as well as the treatment of cancer. Breakthrough immunohistochemistry in cancer diagnosis, prognosis and treatment orientation brings high efficiency to cancer patients.
