Patients with cervical precancerous lesions usually do not show obvious symptoms or only have symptoms of general cervicitis, such as increased leucorrhea, and some complain of blood in the leucorrhea or a small amount of vaginal bleeding after sexual contact. It is reversible, i.e. part of the lesions can disappear naturally, while some have disease progression or even cancer. Its reversibility and progression are related to the extent and degree nature of the lesion. One is bleeding after sex. 70% to 80% of cervical cancer patients have this symptom. The second is cervical erosion. Young women with cervical erosion left untreated for a long time or still have cervical erosion after menopause should be taken seriously. Third, contact bleeding, bleeding after sexual intercourse or uterine bleeding after gynecological internal examination are signs of cervical precancerous lesions. Fourthly, mixed bleeding in the leucorrhea. Except for uterine bleeding caused by IUD, women with long-term mixed bleeding in the leucorrhea should be examined promptly. Medical statistics show that about 15% of patients with cervical precancerous lesions will develop into cervical cancer, and it takes about 10 years to develop from precancerous lesions to cancer, so patients with cervical precancerous lesions have plenty of time for effective treatment. Eighty percent of cervical precancerous lesions can be cured through early detection and early treatment. In addition, women who have sex must receive regular gynecological checkups, try to achieve timely, thorough and standardized treatment for gynecological diseases, maintain good hygiene habits in general, and pay attention to health care and hygiene in sexual behavior. women under 20 years old should have regular gynecological checkups, and women over 20 years old should insist on gynecological checkups and colposcopy at least once every one to two years. The common causes are as follows; 1. Inappropriate sex life Some women have a premature sex life or some unclean sex life, which can lead to the occurrence of cervical cancer disease. Women who do not have sex usually do not suffer from cervical cancer, but the earlier they have inappropriate sex, the more likely it will lead to cervical cancer in the future. Sexual confusion (including both male and female), young age of first intercourse, matrimonial factors, cervical erosion, viral infection (HSV-2, HPV), etc. are high-risk factors for cervical cancer. 2.Cervical inflammation and hormonal abnormalities If women suffer from cervical diseases without good treatment, it is very likely to lead to the occurrence of cervical cancer, if there is long-term cervical damage, skin rupture, erosion and inflammation, it may turn into early cervical cancer cells. According to a survey, abnormal secretion of luteinizing hormone (a female hormone) can change the stability of cervical epithelial cells, causing abnormal changes and leading to the development of cervical cancer cells. 3.HPV infection There is also HPV infection, which is also one of the more serious causes of cervical cancer, so patients must pay attention to this factor. High-risk human papillomavirus (HPV) infection is the main factor triggering cervical cancer, and more than 90% of cervical cancer patients are accompanied by high-risk HPV infection. When HPV infection persists, cervical cancer can be triggered by factors such as smoking, use of birth control pills, and sexually transmitted diseases. This process is long, that is, it takes a relatively long time to develop from HPV infection to precancerous lesion, i.e. CIN, and it also takes a long time to develop from CIN to cancer. 4.Smoking Smoking will increase the chance of cervical cancer because it will reduce the body’s immunity and accelerate the development of cervical cancer cells, in addition, some carcinogenic substances produced by smoking may also lead to the development of cervical cancer cells. 5.Low immune function Long-term strain, staying up late with irregular life, or suffering from chronic diseases, thrombocytopenia, anemia, diabetes, excessive weight loss, etc. How is precancerous cervical lesion caused? After understanding the above, do women friends have a deeper understanding of cervical cancer disease? Usually, women friends should actively carry out prevention and care, and develop good living habits to avoid cervical cancer, which is a serious disease. The actual cervical warts are caused by the human papillomavirus (HPV) infection and are transmitted through sexual contact, mostly in young women. The symptoms of cervical warts often start out as a few soft, light-red papules that gradually increase in size and tend to fuse or overlap with each other, with an uneven, wart-like surface. The cervical warts symptoms can be itchy, burning or pressure. Vaginal and cervical warts may be associated with painful intercourse and increased leukorrhea. In order to prevent the occurrence of this disease, it is necessary to eliminate all unclean sexual intercourse, do not share underwear with others, bath towels, do not go to the public bathroom bath. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. If I or my husband is suffering from other STDs, I should also go to the hospital to check if I am infected with the condyloma acuminatum virus.
