1. What are the ways I can get HPV? HPV can be contracted through almost any sexual contact, sometimes even oral sex. Condoms decrease the risk by about 70 percent, but since any genital contact can spread HPV, the skin not covered by a condom puts you at risk. Most people with HPV show no symptoms. This means that practically anyone-from your husband to your one-night-stand-could pass along HPV.

2. What strains of HPV cause cervical cancer? There are about a hundred different types of HPV, but only a few cause cancer. Most cases will clear up on their own with no treatment. Gardasil protects against types 16 and 18, which cause about 70 percent of cervical cancer cases, and types 6 and 11, which are responsible for about 90 percent of genital warts cases.

3. How can I protect myself against HPV and cervical cancer? Condoms can help protect against HPV and the Gardasil vaccine will be a big help against it as long as you don't already have the strains that cause cervical cancer.

The American Cancer Society outlines other risk factors for catching HPV and developing cervical cancer as well. They include smoking (which weakens your immune system), having sex at an early age, many sexual partners, a partner who has had many partners, sex with uncircumcised males, HIV or Chlamydia, poor diet or family history of cervical cancer. Doctors say women will not develop cervical cancer without first contracting HPV, so the best line of defense is to not get HPV at all.

4. What's the deal with the HPV vaccine? Gardasil was approved by the FDA for girls aged 9-26. They recommend getting vaccinated before you're sexually active, since the longer you wait the more likely it is that you'll already have HPV. The vaccine is given as three separate shots over six months and costs $360, not including the cost of the doctor's office visit. Most insurance companies cover the costs, but check before you are vaccinated. Merck also has a plan for qualified women to be vaccinated for free. So if you're uninsured or your insurance doesn't cover it, talk to your doctor about this program. Many Planned Parenthood centers also carry Gardasil and the price will depend on your insurance coverage.
