Eight virus types cause almost all cervical cancer

LONDON (Reuters) – Scientists have identified the eight human papillomavirus (HPV) types responsible for more than 90% of cervical cancer cases worldwide and say they should be the targets for the next generation of vaccines. Drugmakers GlaxoSmithKline and Merck & Co. already make vaccines against HPV strains that cause many cases of cervical cancer, which is the second most common cancer in women worldwide and is expected to kill 328,000 this year.
