At least 530 000 new cases of cervical cancer are diagnosed worldwide each year; and 80% of these cases occur in the developing world. Worldwide, cervical cancer is the third most common cancer among women and causes more deaths than any other cancer – approximately one death every 2 minutes. In 2010, there were 2851 new cases of cervical cancer in the UK. The highest rates are generally in Scotland, Wales, the Midlands and North England, and the lowest rates are in South and East England. In the UK between 2008 and 2010, an average of 20% of cervical cancer cases were diagnosed in women aged 65 years and over. The estimated annual incidence of CIN among women who undergo cervical cancer screening is 4% for CIN1, and 5% for CIN2 and CIN3.
Cancer of the vulva is rare and, when coupled with cancer of the vagina, accounts for less than 1% of all cancer cases and 6% of gynaecological cancers diagnosed in women in the UK. In 2010, 1200 new cases of vulval cancer and 280 cases of vaginal cancer were diagnosed.
