Cervical cancer vaccination: Why is it absolutely necessary for young boys and girls?
It usually takes 10–20 years for cervical cancer to develop after HPV infection. So if one can prevent cancer causing HPV infection in the first place and cervical precancerous changes in the cervical cells, eventually, cervical cancer can be prevented. Since we know that cervical cancer is caused by HPV infection, vaccines have been developed to prevent major cancer causing HPVs such as HPV 16 and 18 in addition to others.
