What is the Role of Protein Markers in Cancer Diagnosis?
In cancer diagnosis, protein markers help in the characterization of tumors. For example, the presence of certain markers can indicate the tissue of origin, such as PSA (Prostate-Specific Antigen) for prostate cancer or CA-125 for ovarian cancer. Additionally, markers like p53 and Bcl-2 can provide information regarding the prognosis and potential response to therapy.
