New Vaccine For Cervical Cancer

Gynecologists like Dr. Bill Brown have long known the cause of cervical cancer, "Ninety-nine percent of cervical cancers are caused by human papilloma virus."

It's a virus that causes genital warts and cancer of the cervix. Each year, scores of women are diagnosed with the cancer because they unaware of being infected with HPV. A virus that most people are unaware they have.

But now researchers have develop a vaccine they say kills its viral culprit, "We don't get rid of the virus, we just destroy the affected cells from developing," tells Dr. Brown.

Women can also prevent contracting the virus by taking a vaccine. Doctors expect the vaccine to be out within 5 years. They say it's promising, but still the most effective tool against cervical cancer is a yearly pap smear. The vaccine will be one of several preventative tools.
