Both biopsy and pathology are important, and the severity of the two is not comparable. Pathologic examination is an examination to determine the benign or malignant nature of the lesion and is one of the gold standards for clinical disease diagnosis. For malignant tumors, the type must be determined by pathological examination before further treatment such as radiation and chemotherapy can be done to facilitate the guidance of other subsequent treatment modalities. Biopsy, short for biopsy histology, is a small surgery that needs to be done to remove a small portion of highly suspicious diseased tissues or tissue structures that are most prone to lesions before pathological examination, and send them for pathological examination, so biopsy is an auxiliary diagnostic tool. The two may or may not have the same results, and the specific conclusions need to be analyzed and judged by the clinician according to the situation.
