Can puncture determine whether a tumor is benign or malignant?

Puncture generally refers to puncture biopsy, which can usually determine whether a lesion is benign or malignant but should be performed under the guidance of a professional doctor. Puncture biopsy typically involves extracting tissue from the lesion through puncturing and then conducting a pathological tissue biopsy. During the examination, the location of the lesion is usually determined through physical examination, ultrasound, CT, and other diagnostic methods. A puncture needle is then used to obtain the lesion tissue for testing. Based on the test results, doctors can distinguish whether the lesion is benign or malignant. If the lesion is benign and there are no accompanying symptoms of discomfort, special treatment may not be required initially, but regular follow-ups at the hospital are necessary. However, if the lesion is malignant and accompanied by symptoms such as pain and swelling, surgical treatment such as lesion resection may be necessary. After surgery, attention should be paid to wound care, avoiding water and bathing for a short period to prevent infection. If any discomfort occurs, medical attention should be sought promptly.
