The Effect of Hpv (Human Papilloma Virus) Vaccine
HPV vaccine Introduction
The human papilloma virus (HPV) causes infection with certain species of human papillomavirus associated with the development of cervical cancer, genital warts, and some less common cancers. According to a recently survey, cervical cancer has become a second commonest female cancer worldwide. The World Health Organization (WHO) states that 80 percent of deaths from cervical cancer occur in developing countries. In Hong Kong, cervical cancer ranks the 4th most common female cancer which kills over 400 females every year. Moreover, there is a decline in the age at diagnosis among the patients which means cervical cancer is no longer a disease that is far away from us.
The reasons occurring cervical cancer:
The human papilloma virus (HPV) Cervical cancer is a long-term disease caused by an infection of epithelial tissue of cervix. Then it may become an epithelial cell dysplasia. Normally, 70% of cervical cancer is caused by two HPV viruses which are HPV 16 and 18. The HPV viruses would infect the cell through squamous-columnar junction or the hurt transformation zone. Finally, after a long period of time, it may develop into cervical cancer.
Too young to have sexual experience The squamous-columnar junction of a female usually distribute outside of the cervix when they were young. As their ages increase, the squamous-columnar junction will move towards the uterus. The more far away of the squamous-columnar junction, the more easily to infect the HPV viruses. Thus, if the women have sexual behavior when they were too young, they may have a higher tendency to get cervical cancer when they grow up.
Ways to prevent cervical cancer:
The human papilloma virus (HPV) vaccines There are already two different HPV vaccines occur in the city, including the Gradasil MSD and the Cervirax GSK. Normally, both of them can nearly 100 percent successfully prevent the infection of the HPV 16 and
