Generally speaking, the results of neck biopsy can come out in 3~4 days at the earliest, and it takes about 7 days if it is slow. Neck biopsy is a commonly used pathological examination for neck lesions in clinical practice, which can clarify the nature of the disease and determine the benign or malignant nature of the disease, so as to facilitate the formulation of the next treatment plan. Puncture biopsy is the gold standard for diagnosis. The results are usually available in 4~6 days, and the time required varies with the efficiency of each hospital. If an immunohistochemistry test is done it is usually more than 7 days. Patients who have had a neck puncture test should strengthen nutrition after the test, eat a light diet, eat more high-quality protein, avoid spicy and stimulating food, quit smoking and drinking to facilitate the recovery of the wound.
