vaccine can prevent cervical cancer

What is Cervical Cancer?
 Abnormal cells on the cervix
 Like all cells, cervical cells can change
 Changes in cervical cells usually occur slowly,
over many years
 Some changes go away on their own
 Some can develop into cancer (if not found and
treated)
The Good News
 We have known for many years that finding
cervical cancer early saves lives
 80% reduction in mortality since 1960
 Pap tests find the cancer early
The Good News
A 1943 study following first Pap test in 1928, showed
that:
 cervical cancer could be diagnosed by a Pap test
 that if found early enough, cervical cancer
can be cured
The Ontario Cervical
Screening Program (OCSP)
 Women age 21 – 70
 Who have been
sexually active
 Every three years
Human Papilloma Virus (HPV)
 HPV is found in both men and women
 there are more than one hundred “types” of
HPV divided into:
‐
high-risk HPV: can cause cancer
‐
low-risk HPV: causes genital warts
Human Papilloma Virus (HPV)
All cervical cancers are caused by HPV:
 Types 16 and 18
70% of cervical cancer
 Types 6 and 11
90% of genital warts
Human Papilloma Virus (HPV)
 Very common
 Can cause cancer
 Transmitted skin-to-skin genital
contact and/or during sexual
intercourse
How is HPV Spread?
 Skin-to-skin contact, most often during
penetrative genital contact (vaginal or anal sex).
 Other types of genital contact
 Condoms may decrease risk, but don’t eliminate
risk
How Common is HPV?
 Infection can spread rapidly after
onset of sexual activity:
36% or more infected
after 3 years
We Can Prevent HPV Infection
HPV vaccine
 Approved for women age 9 - 45
 Recommended for men age 9 - 26
 Available to grade 8 girls at no cost through public
health school program
 3 doses needed

Things to Remember…
 HPV vaccine prevents infection
 HPV vaccine does not replace Pap tests
 Pap test detects cell changes before they
become cancer
 Almost all cervical cancers can
be prevented if cell changes are
found early and treated
