TCT is a kind of cytology test, which is more accurate than the previous Pap test, but it is still limited as a preliminary screening test. TCT is a cytological test by taking some tissues of the cervix, mainly the surface cells and then doing the test. Because some of the cells on the surface are not cancerous, but deeper tissues can be cancerous, so a normal TCT does not completely rule out cervical cancer. When you get the result, the doctor will usually give you an analysis, including the combination of clinical symptoms. You will be informed that TCT is a preliminary screening with a very small number of missed diagnoses and you need to review it regularly according to the situation. Intercourse 24 hours before the TCT, recent placement of vaginal suppositories or douching with medication can affect the test results. It is important to know more about the test before the test and to choose a non-menstrual period for the test. It is better to treat the inflammatory period before the test to avoid affecting the interpretation of the test results. The most important symptom of cervical cancer is contact vaginal bleeding, which should be further examined after it occurs. The most important symptom of cervical cancer is contact vaginal bleeding. Any test can be biased or have specific changes, so it is very rare to have a normal TCT but have cervical cancer. Therefore, it is very rare to have TCT but have cervical cancer. Do not think that TCT is meaningless because of rare cases.
