Can a blood test detect cervical precancerous lesions?

In recent years, the incidence of many gynecological diseases has been increasing. The reason for this is largely related to the increasing social pressure and the increasing awareness of late marriage. In addition, more and more young people and childless women are also troubled by cervical erosion, and cervical erosion is becoming younger and younger.

1. The significance of cervical disease screening:

Cervical precancerous lesions are a type of malignant tumor that seriously endangers women's health. In recent years, the incidence rate has been steadily increasing and is becoming younger. Cervical precancerous lesions are one of the common gynecological malignancies, and the incidence rate ranks second among female malignant tumors. According to worldwide statistics, an estimated 466,000 cases of cervical precancerous lesions occur each year. 80% of these cases occur in developing countries. Epidemiological data from developed countries and some developing countries that have established screening systems show that the incidence and mortality of cervical precancerous lesions and invasive cancer have dropped significantly.

Carrying out a census of people with cervical diseases is conducive to the early detection, early diagnosis and early treatment of cervical diseases. If the disease is treated promptly and thoroughly, the lesions will disappear and the body will quickly recover.

2. The best starting and ending age for screening:

Although cervical precancerous lesions can also occur in young women around 21 years old, they are more common in women over 40 years old. It usually takes about 10 years from the discovery of high-grade lesions to the development of cancer. The peak period of precancerous lesions is around 30 years old, so the starting age for screening can be considered to be 25-30 years old; the risk of cervical precancerous lesions after 65 years old is extremely low, so it is generally not recommended to perform routine cervical precancerous lesion screening for women over 65 years old.
