(CNN) - An annual cancer report finds overall cancer death rates are declining in the United States, but the number of cases of some cancers related to the human papilloma virus has gone up, despite the fact there are vaccines available to prevent the HPV infections that can lead to cancer.

The first vaccine, Gardasil, was approved by the Food and Drug Administration in 2006.

The vaccine protects against strains of the HPV virus that can cause cervical cancer and genital warts.

Another HPV vaccine was approved in 2009.

The annual cancer report is a collaboration between the Centers for Disease Control and Prevention and several major U.S. cancer groups.

The report concludes there's clearly a need for more prevention efforts for HPV-related cancers including getting more people vaccinated.
