At present, the following tests are commonly used to diagnose gynecological tumors. 1.Vaginal exfoliative cell examination Including vaginal smear and cervical scraping examination. The cells obtained from the vaginal vault may come from the fallopian tubes, uterine cavity, cervical canal and vagina itself. Vaginal discharge smear, is the easiest method, but the exfoliated cells may be morphologically distorted if they are old and not easily identified or confused with each other. Cervical scraping (currently thin layer liquid-based cytology, or TCT, is mostly used in large and medium-sized cities), on the other hand, involves the application of a special sampler to scrape cells from the surface of the cervix and from the cervical canal. The cells obtained by this method are relatively fresh and can be distinguished from normal cells and malignant tumor cells according to cell morphology and nucleus size. 2.Biopsy The biopsy method is to take a small piece of tissue with biopsy forceps for examination. After the tissue is sectioned and stained, not only the characteristics of individual cells can be observed, but also the connection and arrangement of cells can be seen, which makes the diagnosis of tumor more reliable. The female genital organs are either exposed on the surface of the body or have cavities connected to the outside world, an anatomical feature that provides favorable conditions for biopsy. When the vulva, vagina, cervix and uterine cavity are suspicious in appearance or symptomatically suspected of cancerous tumor, taking biopsies can make a definite diagnosis. Sometimes, for the masses in pelvic cavity, it is also necessary to obtain tissues by puncture with fine needle under the guidance of ultrasound and CT. Ultrasound examination is to diagnose diseases by using ultrasound emitted from inside the human body and receiving its echo signal, and B-type ultrasound can show the image of deep pelvic organs, which is of great value for the diagnosis and differential diagnosis of gynecological tumors. 4.X-ray examination Certain gynecological tumors, such as ovarian mature teratoma with teeth or bone fragments inside the tumor; ovarian epithelial carcinoma with sand granules or calcification inside the tumor, can show teeth, bone fragments or calcification shadow through X-ray examination, which can help to diagnose. In addition, there are some special X-ray examinations, such as uterine iodine oil imaging or gastrointestinal imaging, which can show the morphology of uterine cavity, the morphology of intestinal cavity and its relationship with genitalia, and provide help to diagnosis. 5.CT and MRI are two new imaging methods. For endometrial cancer and cervical cancer, they can help determine whether the tumor has extended and metastasized. 6.Endoscopy The main endoscopes used for gynecological tumor diagnosis are laparoscopy and hysteroscopy. Laparoscope is a kind of endoscope that can see the organs in the abdominal cavity. The outer diameter of laparoscope is only about 1 cm, and it only needs to make a small incision of about 1 cm on the abdominal wall and then extend the lens into the abdominal cavity to clearly observe the external appearance of the pelvic and abdominal organs, especially when the pelvic mass is not sure that it is a gynecological tumor, or when the exact site of tumor occurrence and the scope of tumor metastasis are not clear, the diagnosis can be clearly made through laparoscopy. Hysteroscopy is a kind of endoscope that reaches into the uterine cavity through the cervix to see the uterine cavity structure, especially for submucosal fibroids and endometrial lesions, which is a very valuable diagnostic method.
