Tumor Puncture Will Stimulatetumor Metastasis?

The reason why many patients and family members are afraid of puncture is first of all intuitively. Although the puncture is a needle, the length of the needle is usually more than 10cm and the penetration is very deep, which makes many patients feel scared. Secondly, the patients who need puncture are basically determined to be tumors, mainly to further detect the shape of the cancer cells. For the patient, the result of the diagnosis and treatment is as if he has been sentenced to death. At this time, he can be treated as he should be, so why bother to have another puncture?

In addition, some people think that puncture will pierce the tumor and cause cancer cells to metastasize. This is actually nonsense. There are three reasons:

①Generally, the needle for tumor puncture is small (usually 0.4-0.7 mm), and the trauma to normal tissues and tumors is also small.

② The puncture examination time is very short. Once the diagnosis result appears, the doctor will immediately take corresponding treatment measures. Cancer cells are too late to metastasize.

③The puncture site is generally far away from the larger blood vessels, and generally does not cause cancer cells to enter the blood.

According to the "Consensus of Chinese Experts on Thoracic Tumor Biopsy" released in 2018, puncture can reduce the probability of misdiagnosis and missed diagnosis, and plays an important role in subsequent treatment. For example, lung cancer, because the imaging test results are only shadows and small nodules, if you want to make a more accurate diagnosis, you must get a sample of live tumor cells.

Therefore, puncture is very important in the diagnosis and treatment of tumors. Don't listen to rumors and resist needle biopsy.
