Nowadays, the increase of premarital sex and the trend of younger age, as well as sexual confusion has become a social issue of concern to the whole society. In fact, early sex and too many sexual partners for women are the culprits of the younger cervical cancer incidence among women in recent years. Many cases of cervical cancer are caused by sexually transmitted infections, and the more sexual partners you have, the greater the probability of sexual diseases and the higher the incidence of cervical cancer. Therefore, it is important to have a healthy sex life, because a healthy sex life can prevent cervical cancer. Can too much sex and too many sexual partners cause cervical cancer? This is a question that is difficult to answer with a simple “yes” or “no”. There is an undeniable link between the two, but it is not a causal one. There is a “bridging” third party between sex and cervical cancer, and it is the human papillomavirus (HPV) infection. Current research indicates that HPV infection is a necessary factor in the development of cervical cancer and its precancerous lesions. HPV infection plays an important role in the development of cervical cancer, so how does HPV infection occur and how is it transmitted? Sexual contact is the main way of HPV transmission, and HPV infection is one of the most common sexually transmitted diseases. The prevalence of HPV infection in the general population is high. It is estimated that the lifetime probability of HPV infection in the female genital tract is 80%, and about 50% of women can detect HPV infection in the genital tract within two years of starting sexual intercourse, especially in young women, where the rate of HPV infection can be as high as 60%. There are many risk factors that influence the transmission of HPV infection. Close personal contact, especially sex, is the main route of transmission of cervical HPV infection. In numerous studies of HPV infection transmission in young women, researchers have found that women having multiple male sexual partners, as well as the number of male sexual partners, are directly associated with the occurrence of HPV infection in women. In summary, healthy sexual behavior can prevent cervical cancer. When a woman has more than four sexual partners, her risk of developing cervical HPV infection is more than four times higher than that of a woman with only one sexual partner. The greater the number of partners in a sexual relationship, the greater the risk of HPV infection. Several studies of sex workers have also confirmed that sexual promiscuity is a high risk factor for the development and transmission of HPV infection. For most girls, cervical cancer is a distant disease. However, the fact that early sex increases their risk of developing cervical cancer later in life is not alarming.
