It has been proven that cervical cancer is an infectious disease that can be prevented and cured in its early stages. The development of cervical cancer has obvious stages, generally through precancerous lesions (i.e. atypical hyperplasia), carcinoma in situ and invasive carcinoma. The peak ages of the three are 30-44 years old, 40-44 years old and 45-54 years old respectively, with a difference of 5-10 years between the ages of each group. This is a slow development process, and since the cervix is inside the vagina, it is easy to be exposed and examined, so cervical cancer is a disease that is most easily detected and diagnosed at an early stage. There is a standardized process for cervical screening and treatment with a three-step screening method: cytology, human papillomavirus testing, and colposcopic localization biopsy. After the cytologic examination, if abnormalities are found, confirming human papillomavirus infection, or suspicious cells are found, including atypical cells, low- or high-grade squamous intraepithelial neoplasia cells, cancer cells, etc., a second diagnostic step is taken: colposcopic localization of a cervical biopsy. Histopathology will confirm the diagnosis. How can prevention and early detection be done for ordinary women? 1. Regular gynecological examinations (including cervical cytology) are very important. At present, many women miss the best time for screening and treatment due to work pressure, time constraint, or due to shyness to ask for medical consultation, reluctance to do gynecological examination and so on. As a result, many patients are found only when infiltrating cancer, which brings many regrets. 2. Special attention should be paid to some clinical manifestations: including contact vaginal bleeding or spotting vaginal bleeding after sex, bloody leucorrhea, sudden change in the amount of leucorrhea traits; 3. Mainly healthy lifestyle.
