Cervical cancer ranks high as the second most common malignancy among women worldwide. In recent years, it has become popular for many high-income women to go to Hong Kong and Macau to get the cervical cancer vaccine to protect themselves against cervical cancer. So when is the best time for cervical cancer vaccination? Cervical cancer vaccination Cervical cancer is the second most common cancer killer among women after breast cancer, but it is also the only cancer that has been cracked so far. It is now clear to the medical community that human papilloma virus (HPV) is the main cause of cervical cancer in women, and 99% of cervical cancers are related to HPV infection. More than 200 types of HPV viruses have been discovered, and there are at least 10 types directly related to cervical cancer, of which about 70% are caused by HPV-16 and HPV-18, and the cervical cancer vaccine is mainly for these two viruses. Because of the difference in ethnicity between the East and the West and the type of HPV attack, the vaccine developed by the West is not entirely suitable for use in China. At the same time, because the vaccine requires strict conditions for preservation and is prone to leakage during transportation, it is most suitable to be given in a qualified hospital in Hong Kong if possible. What is the efficacy of cervical cancer vaccination? Cervical cancer vaccination is a kind of vaccine to prevent cervical cancer, as its name suggests, it is used for injection to prevent cervical cancer, but due to the limitation of vaccine technology and other factors, the efficacy of this vaccination cannot be guaranteed. As we all know, cervical cancer is one of the common malignant tumors in women, and if left untreated, it will often endanger the life of the patient, but whatever the disease is, it is basically preventable, and cervical cancer can also be prevented, such as cervical cancer vaccination. The so-called cervical cancer vaccination is actually a vaccine to prevent cervical cancer, and the main purpose of the vaccine is to prevent the human papilloma virus infection that causes uterine cancer.
