It is a professional department for the diagnosis and treatment of female gynecological diseases. Among them, common gynecological tumors are vulvar tumors, vaginal tumors, uterine tumors, ovarian tumors and fallopian tube tumors. Uterine and ovarian tumors are more common, and vulvar and fallopian tube tumors are rare. When there are common symptoms of gynecological tumors, it is necessary to go to the hospital for examination in time, and make judgments through pelvic examination and various auxiliary examinations. Tumors refer to new organisms formed by the proliferation of local tissue cells under the action of various tumorigenic factors, because these new organisms are mostly space-occupying massive protrusions, also known as neoplasms, before the treatment of tumor patients, The tumor needs to be sampled and analyzed, so that the right medicine can be prescribed. There are two common methods. One is to take samples directly through a scalpel, and the other is to use a syringe to take samples.
