In Europe, 52 000 cases of cervical cancer occur yearly (estimates for 2004). Sixty-five per cent, or 34 008 of cancer cases, are attributed to HPV16; 71·5% (or 6·1% more) can be attributed to HPV16 or HPV18. Almost 88% of cervical cancers are attributed to one of eight HPV types. Adapted from Munoz, 2004 and Arbyn, Ann Oncol 2007a,b [75–77].
