How accurate is biopsy pathology in determining cancer?

The accuracy of biopsy pathology in determining cancer is generally as high as 80%-90%.

Biopsy can obtain cytological samples of diseased tissues, and perform microscopic observation and analysis of the samples through pathological examination to determine the nature of the lesion and diagnose cancer. Compared with other examination methods, needle biopsy has higher specificity and sensitivity, can more accurately detect the presence and type of cancer, but also can provide other important pathological information, such as tumor histological subtype, malignant degree and relationship with other lesions, so its accuracy rate can usually be as high as 80%-90%.
