[How do we know the diagnosis -- scored cervical cancer?

According to the history and clinical performance, in particular in contact bleeding, we should first think of the possibility of cervical cancer. should do a detailed body check and gynecological examinations, and the following examinations : (1) cervical smear is early detection of cervical lesions and early cervical cancer main method. But the attention on the position correct and careful examination, it will be 5% ~ l0% of the false-negative rate, and should be combined with clinical situation, and regular check this method for screening. (2) iodine test normal vaginal or cervical squamous epithelium contains abundant glycogen, with povidone - iodine to be brown, and cervical columnar epithelium, cervical erosion and abnormal squamous epithelium (including squamous metaplasia, dysplasia, carcinoma in situ and invasive carcinoma) glycogen not exist, it is not color. Clinical use of vaginal cervical cpeculum exposed, to remove surface mucus to povidone - iodine cervical smear and domes, If found to be normal iodine negative zone in this area can obtain biopsy sent for histopathologic examination. (3) cervix and cervical biopsy examination in the cervical smear for class III-IV above smear, But cervical biopsy was negative, in a column of cervical squamous junction of 6, 9, 12 and 3:00 4:00 obtain biopsy, or iodine test is not coloring and carcinogenesis suspicious site, from various organizations, and biopsy Application small scratch or PKI scraching cervical, scrapings were sent for histopathologic examination. (4) colposcopy colposcopy no direct cancer diagnosis, but can assist in the selection of the site for biopsy of cervical biopsy. According to statistics, if the colposcopy with the assistance of biopsy in the diagnosis of early cervical cancer accuracy rate to 98%. However, colposcopy can not replace smear and biopsy examination, we can not find cervical lesions. (5) resection of cervical cone biopsy in check not sure whether invasive, it may taper for cervical surgery. However, the current diagnosis of cervical cone resection has been rarely used. When cervical cancer is established, under specific circumstances, for lung X-ray film, lymphography, cystoscopy, rectal endoscopy. to determine the clinical stage of cervical cancer.
