Did you know that cervical cancer is the second most common
type of cancer in women? Or that according to the National Cervical CancerCoalition (NCCC), 12,000
women are diagnosed with cervical cancer each year and 4,000 will die? How
about that the Human Papillomavirus (HPV) is found in 99% of cervical cancers?
The good news is that cervical cancer is one of the most
preventable cancers. January is cervicalhealth Awareness Month and
today, we’ll take a look at HPV.
HPV
is a type of virus that can cause abnormal growth (for example, warts) and
other changes to cells. Infection for a
long time with certain types of HPV can cause cervical cancer. It can also play a role in some other types
of cancer such as anal, vaginal, vulvar, penile, oropharyngeal and squamous
cell skin cancers. There are over 100
types of HPV, but experts have determined that 14 of these types actually cause
cervical cancer.
HPV is shared through skin to skin contact and not through
bodily fluid exchange. There are
approximately 6 million new cases of HPV each year with at least 20 million
people estimated as currently infected.
The National Cervical Cancer Coalition explains that to
better understand HPV and its effect on cervical cancer, visualize the cervix
as soil and high risk HPV as the seed.
There are other co-factors that can increase the risk of cancer, which
can be thought of as fertilizer.
Some of the
co-factors include: smoking, long-term use of oral contraceptives, a weakened
immune system, power diet (lack of Vitamin A and Folic Acid), presence of other
sexually transmitted infections such as Chlamydia, history of many sexual
partners, sexual activity at a young age, male partners without circumcision
and possibly having many children.
What the best defense against HPV? Experts are now
recommending that girls around the age of
11-13, who are not yet sexually active, receive a vaccination against HPV. The vaccination is given in three doses over
six months and guards against HPV Type 16 and Type 18. Genotyping for HPV 16 and Type 18 has proven
responsible for 70% of cervical cancer worldwide. When boys are vaccinated by a product
produced by the company Gardasil® the vaccination also
protects against Type 6 and Type 11 which causes about 90% of genital warts
cases in men and women. The vaccination is also recommended for homosexuals as
a guard against oral and anal cancers.
Approximately 30% of oral carcinomas
can be attributed to HPV and HPV Type 16 has been linked to some head and neck
cancers.
According to Dr. Kristen Jacobs, Director of Cytopathology
and Reproductive Medicine at The Medical Foundation, “the vaccine is effective
and I do encourage that girls get the vaccine ; however, it hasn’t proven
effective against all carcinogenic types which means that women can still
become infected with a type they’ve not been vaccinated against.”
Dr. Jacobs recommends that the best screening for women is
to have Pap smears because the Pap test finds changes in the cells of the cervix
that are not normal. Around the age of
30, a woman should have a Pap test and an HPV test to establish a baseline for
future testing. It isn’t recommended for women younger than 30-years-old to
have an HPV test because often the body will naturally clear itself of some of
the viruses. Typically, women ages 35-55
are diagnosed with HPV.
The Medical Foundation has the capability to perform
Genotyping for HPV Type 16 and Type 18 using the Roche cobas® HPV test. The Foundation also performs testing on
approximately 85,000 Pap smears each year. If you are a healthcare provider and
would like more information about the Roche cobas® testing provided by the
Foundation, or information about SurePath or ThinPrep Pap tests, please email info@sbmf.org or contact your marketing
