Cervical cancer is one of the most common malignant tumors in women, and its high incidence age is from 30 to 55 years old. In recent years, there are data showing that its incidence age is trending younger, and there are even women in their 20’s who have cervical cancer in clinical practice. However, with the continuous progress of medicine, early detection of cervical cancer has become possible, especially the widespread use and promotion of cervical cytology (TCT) and human papilloma virus (HPV) examination in recent years, which makes the detection of cervical cancer and precancerous lesions possible. At present, the cause of all cancers in clinical practice, only cervical cancer is determined, which is caused by what we call human papillomavirus infection, or what we call HPV infection. Cervical cancer screening is generally referred to as liquid-based thin layer cytology (TCT) and human papillomavirus typing (HPV) test. Based on the results of the two tests, lesions are detected early and treated promptly. HPV infection, also known as human papillomavirus infection, is divided into various types, including high-risk infection and low-risk infection, especially the high-risk infection, especially the type 16 and 18 infection, which may lead to cervical lesions and even cervical cancer if it is a long-term, persistent infection. However, don’t be nervous yet, even with HPV infection, most HPV infections can be cleared up as long as they are closely observed, properly strengthened and the body’s immunity is enhanced, through the body’s immune system and certain medication. Only a small percentage of women with HPV infection will have cytological TCT changes, which can be detected and treated in time according to TCT results. Before the cervical cancer screening, we also need to pay attention to: 1. Do not have sex one day before the examination; 2. Do not douche the vagina with lotion, vaginal medication, vaginal suppositories, creams, etc. before the examination. 3. If vaginitis is found during the examination, vaginitis should be dealt with first and cervical cancer screening should be done after the treatment of vaginitis is cured, so as not to affect the accuracy and correctness of the examination results. Therefore, as long as we insist on annual gynecological examination and necessary cancer screening, we can detect cervical lesions and precancerous lesions in time, diagnose and deal with them in time, and prevent them before they happen. May all of our female friends have a healthy body, happy family and a bright future.
