Is Tumor Puncture Harmful To The Body?

Tumors are classified as benign and malignant. Tumor metastasis refers to the malignant tumor cells from the primary site, through the blood circulation or lymphatic system "run" to other places, or directly shed to other organs, continue to multiply and grow, forming tumors of the same nature. In theory, any stimulation of cancer tissue, including acupuncture, excision, biopsy or other tests, injection of anesthetic drugs, or even forceful rubbing and squeezing, will cause cancer cells to shed and enter the bloodstream, causing hematological metastases. About 50 percent of patients with malignant tumors do have detectable cancer cells in their blood. Although cancer cells can enter the bloodstream, they are difficult to survive in the blood because the patient is stimulated by cancer cells and produces corresponding antibodies and sensitizing lymphocytes. When cancer cells enter the blood, the first antibodies they encounter reduce their activity. The cellular immune system also releases large amounts of lymphokines to kill or kill them. Even if some patients with tumors have cancer cells in their blood, it does not necessarily mean that metastatic cancer will form. Only when the immune function of the body is reduced, or the number of cancer cells shed exceeds the body's ability to clean itself, the cancer cells that escape the net will "settle" in some parts of the body, and thus grow into metastatic cancer. This is an extremely complex process.

Does needle biopsy lead to local implant metastases of malignant tumors? Medical experts say no. In addition to the above reasons, generally speaking, the needle used for tumor puncture is small (e.g., the needle used for breast puncture is only 0.9 mm in diameter), and the trauma to normal tissue and tumor is minimal. Secondly, the puncture examination does not take a long time, the diagnosis can be made quickly, once the diagnosis is made, the appropriate treatment measures will be taken immediately. Third, the puncture site is usually far away from larger blood vessels, giving the cancer cells little chance of entering the bloodstream. Therefore, there is no tumor metastasis after puncture. Puncture examination has no adverse effect on prognosis.
