What is HPV? The Importance of HPV Vaccine


What is HPV?

HPV refers to human papillomavirus. Molecular epidemiological studies have confirmed the close relationship between HPV infection and cervical cancer, and studies on cervical cancer specimens have found that more than 99% of cervical cancers have HPV infection, with HPV types 16 and 18 having the highest infection rate of about 70%.

HPV type 16 infection is most commonly found in squamous cervical cancer, while type 18 is most commonly found in cervical adenocarcinoma. Therefore, HPV vaccine is currently available to prevent and treat the infection and thus prevent the occurrence of cervical cancer.

Depending on the severity of the disease caused by HPV infection, there are low-risk and high-risk types. Low-risk HPV infection mainly causes benign lesions, such as warts and flat warts; high-risk HPV infection can lead to the development of malignant tumors of the reproductive tract, including cervical cancer.

HPV causes malignant tumors in women: cervical cancer

Among women aged 30-44, cervical cancer is a malignant tumor with an incidence rate second only to breast cancer. According to statistics, there are about 528,000 new cases of cervical cancer and 266,000 deaths related to cervical cancer worldwide every year. Eighty-five percent of these cases occur in developing countries.

HPV infection is the primary factor in cervical cancer, although it is said that only the high-risk HPV types are lethal. But don’t take any chances, 70% to 80% of women have been infected with HPV at least once in their lifetime, and the incidence is getting younger. If you don’t go to the hospital, you really don’t know if you have a high-risk or low-risk infection. Therefore, everyone should try to get vaccinated against HPV.

HPV vaccine can prevent cervical cancer and other diseases caused by HPV

People like to call HPV vaccine as cervical cancer vaccine, in fact, HPV vaccine can prevent not only cervical cancer, but also other diseases caused by HPV. For example, genital warts, vaginal cancer, penile cancer, anal cancer and oropharyngeal cancer.

Increasing pre-cancer screening helps prevent cervical cancer

As the incidence of cervical cancer continues to rise, the screening system for cervical cancer and precancerous lesions is becoming more and more sophisticated and important. Since the association between HPV and cervical cancer has been confirmed, HPV-based diagnostic methods are gradually being promoted in cervical cancer and precancerous lesion screening. Increasing pre-cancer screening is extremely important for early detection, early prevention and early treatment of cervical cancer!
