According to a summary of research from University of New South Wales, http://www.eurekalert.org HPV’s known to cause cervical cancers were found in 39 percent of the specimens of ductal carcinoma which had not invaded other tissues, and 21 percent of the type which was invasive.
Reports from fourteen other nations showed HPV positive breast cancers in from 4 percent up to 86 percent of the breast cancers which they had studied.
HPV’s are known to be causal in 90 – 95 percent of cervical cancers.
The stakes for females are high. Thousands die each year from cervical cancers. In 2004, over one million women found out that they had breast cancer. It was fatal for half a million.
The current HPV vaccine gives good protection from most (70%), but not all (30%) of the cervical cancer-causing HPV’s. Being intimate only with a partner who is HPV-free remains the best way to avoid getting this STD.
