A clinical examination
1. Vaginal exfoliated cells inspection (inspection of cervical cells scratch tablets) for the early detection of cervical cancer most effective screening method. Most of the early stage of cancer no obvious symptoms, clinical examination alone the naked eye doctors to identify the existence of tumor, so little time early cervical cancer was found. Cervical exposure to the top of the vagina, easy observation and material, currently in clinical right where married women, gynecological examinations or cancer prevention census, conducted routine vaginal examination exfoliated cells, as a screening tool. The diagnosis of cervical cancer early positive rate significantly increased over 90%. In order to improve the accuracy of Pap smear diagnosis, with particular attention to the good parts from cervical squamous epithelium and the columnar epithelium at the junction of material. Since older women scales, columnar epithelium to the junction of the neck upward, in addition to material from the cervical, vaginal smears from the dross, but also from the material of cervical smears to avoid misdiagnosis.
2. Colposcopy colposcopy can be six to 40 times magnification for the observation of cervical vascular and tissue changes can improve diagnosis of carcinoma in situ 7 ~ 10 times, and the pathological diagnosis rate is 78%. Colposcopy choice needle biopsy site inspection to the vaginal cytology smear suspicious lesions were found early the location, scope, nature and extent, but not found scales - junction or extension of the cervical lesions, can not replace the scratch - or cervical biopsy.
3. Cervical microscope photography with 10mm and 35mm 50mm additional extended circle of photographic device, will be received wide image projected on the screen Joseon, a distance of 1m; Scales-all at the junction, no abnormal negative, unusual for suspicious, no scales, in the junction of dissatisfaction. Some of its diagnostic accuracy rate of 93.1%, it is a high accuracy, low cost, ease of application of the new method.
4. The trial of iodine concentration of 2% iodine solution directly in cervical smear and vaginal mucosa, the coloring is not positive, helping to provide needle biopsy site inspection.
5. Needle biopsy of the cervical screening conducted by the check-ups are important elements of diagnosis, but the diagnosis of cervical cancer biopsy is the most reliable basis. In iodine testing or colposcopy suspicious site material for histological examination. If no surface cervical cancer, cervical biopsy needs of the organization sent to histopathological examination.
6. When the resection of cervical cone cells cervical screening films repeatedly blowing positive, and more biopsy of the neck of blowing negative, or have proved to carcinoma in situ, invasive cervical cancer can not be ruled out, Cervical Conization of feasible and sent to the pathology. This method of achieving the objective will be lesion resection, is considered achieve the purpose of the method. After cutting a cone of varying degrees of complications in clinical trials do not use more, as if the surgery can replace hysterectomy.
7. Using fluorescence test cancer and normal tissue absorption and fluorescence-how many different shows different colors of whether cancer diagnosis. Luciferase cancer absorption, fluorescence than the normal tissues strong and dark yellow, violet blue for normal tissue.
8. Scholars biochemical diagnosis of cancer through clinical study found that in cervical cancer patients, lactate dehydrogenase, sugar kinase has increased significantly, especially in the more obvious infiltration, contribute to the clinical diagnosis.
Two other checks
Depending on the specific circumstances of each case can be cystoscopy, rectum mirror, kidney map, IVP, chest, pelvis corresponding inspection, if necessary, a CT scan or MRI, to determine the scope of diseases, select the appropriate treatment methods to improve the treatment, prognosis, is certainly want.
The check-up of service, and triple up, hit cervical local stiffen, coarse, or protuberance of the block. General little uterus. Pregnancy may have different thickness, elasticity disappeared or were massive corporation. Early can be found no other positive.
