HPV vaccination could also protect against breast cancer

HPV vaccination to prevent cervical cancer may have a spin-off benefit in reducing breast cancer in younger women, Australian researchers suggest.

In a study of specimens from women who had previous cervical neoplasia and developed breast cancer one to 11 years later, the researchers showed the same high-risk HPV types were involved, with HPV 18 the most prevalent.

Their work suggests that despite a low viral load, the HPVs were biologically active and had “oncogenic influences” on the breast in some cases, say the authors,
