Cervical cancer is the most common malignancy of the female genital tract, with the incidence being the second most in female malignancy and even the first in some developing countries. Cervical cancer is about 50 tens of thousands of new cases worldwide each year, accounting for 5% of all new cases of cancer, with more than 80% in developing countries. Women over 26 ten thousand die from cervical cancer annually, mainly in low and medium income countries. The new disease cases of China reach 13.15 ten thousand per year, the death number of cervical cancer is about 5.3 ten thousand per year, and the cervical cancer accounts for 18.4% of the death number of all female malignant tumors. Cervical cancer is an important disease which endangers the health and life of women in China.
