In patients with cervical intraepithelial neoplasia grade 1 (CIN1), is it better to have surgery or medication? We met one such patient today who came for consultation. Once you understand the reasoning, you can determine for yourself whether surgery is needed. First of all, 99.8% of cervical cancers are caused by human papillomavirus (HPV) infection, and 95% of women have at least 1 HPV infection in their lifetime, in fact, how many develop cervical cancer? Only 9.9 per 100,000 women. So what is the reason why so few women develop cancer? It is true that HPV is the main culprit, but the human body is not just waiting to die. Women have the ability to “detoxify” themselves and will not let HPV do whatever they want in their bodies. Only a small number of women, due to the number of HPV infections, their virulence, and their low resistance to HPV infection, will cause HPV to remain in the cervical squamocolumnar junction for a long time, usually more than 12 months, before it leads to cervical intraepithelial neoplasia (CIN). It is evident that persistent HPV infection is the real cause of cervical cancer. Second, CIN1 is the earliest cervical intraepithelial neoplasia, which is a low-grade lesion. Less than 30% of CIN1 patients will progress to CIN2, and more than 60% of CIN1 patients will get better on their own, and the basis of improvement is no more persistent HPV infection, and the basis of progress to CIN2 is persistent HPV infection. So as long as you find a way to get rid of the infected HPV and stop getting infected with HPV, the chances of CIN1 getting better will further increase. Third, how to get rid of HPV in the body while no longer being infected with HPV? First, it is important to know how you got infected? This issue is not clear to the individual suffering from the disease, so if the patient himself is clear, eradicate it is. Second, if the patient does not have medical knowledge and cannot figure out how to get infected, insist on using condoms all the time, even though it is not 100% effective, it is better than not using them after all, about 70% of the barrier effect. And there are a variety of ways to get rid of HPV in the body: 1, the simplest way is to use interferon topically, but the efficiency is also the lowest; 2, intramuscular injection of interferon, relatively high efficiency, but the side effects are also relatively increased; 3, intravenous drip drug, more efficient, but the side effects are also greater; 4, surgery, 1/3 of patients will naturally turn negative after surgery, but the chance of re-infection may also be the greatest, in addition Surgery, no matter how big or small, still has risks. In summary, you may understand that the method you need, is the best.
