Does lymphatic cancer biopsy cause metastasis

if the needle is too large and not guided, it can also penetrate the tumor and carry the cancer cells deep into the tumor. or when the needle comes out of the skin after the puncture, the "tunnel" through the puncture may also carry cancer cells into normal tissue, causing tumor metastasis.

however, with the development of technology, the size of the puncture needle head and the "route" of the needle passage are often carefully arranged when puncture is performed in regular hospitals. in general, the needle used for tumor puncture is very small, especially the needle used for breast puncture is very thin, and does little damage to normal tissue and cancer.

in addition, as long as there is guidance during the puncture, the needle will be directly to the center of the tumor, to avoid cancer metastasis. in the puncture route, the needle path design is within the scope of the operation, even if the abnormality is found, it can be removed immediately, and the probability of tumor metastasis after puncture is very small. after local anesthesia, the puncture was performed with little pain, and the puncture hole healed naturally after a few days.

accordingly, no matter what part of the body grew a lump, should listen to the examination arrangement of the doctor, do not worry too much, psychological burden is heavy can delay opportunity of diagnosis and treatment only, make illness add
