How long does it take for a tumor biopsy to produce results?

Tumor biopsy is the normal pathological examination of a tumor. It is the gold standard for the diagnosis of a tumor. After the patient takes out the tumor tissue in the hospital and sends it to the pathology department, the pathologist first fixes the tumor tissue, then embeds it in paraffin, slides it, stains it, and finally observes it under a microscope. Sometimes the tumor cells are difficult to identify, and immunohistochemical staining, genetic testing, etc. are needed. This process is very complicated and time-consuming. Therefore, how long it takes for tumor biopsy to produce results may vary from hospital to hospital, but it usually takes about 1-2 weeks.
