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.
