aim to prevent a future HPV infection
Gardisil & Cervarix
Pap Smear test checks for the changes of cells in the cervix
indicate whether you have an infection, abnormal cervical cells, or cervical cancer
Loop Electrosurgical Excision Procedure (LEEP)
GENITAL WARTS TREATMENT
Cryotherapy- using liquid nitrogen, abnormal, damaged cells are executed by freezing
Electrosurgery- radiating abnormal cells by passing an electric current
Laser Therapy- eradicate abnormal cells with the use of a laser that vaporizes
Effects of HPV upon Society
once one person has it, it spreads causing many people to become infected.

10% to 30% of Canadians are infected with HPV

leads to many people getting genital warts and cancer
INTERESTING FACTS!
warts can appear within months after getting HPV
infection with one type does not build immunity to other types
having multiple partners increases your risk of infection
cancer often takes years to develop after a person gets HPV
