Cervical cancer is the most common malignant tumor of female genitalia. The onset age is mostly 40-55 years old, followed by 60-69 years old. Its incidence is related to early marriage and childbearing, sexual dysfunction and some viruses transmitted through sexual intercourse (such as human herpesvirus II, human papillomavirus, human cytomegalovirus, etc.). ), especially HPV 16 and 18. The occurrence of cervical cancer often goes through a long process, from chronic cervicitis (especially cervical erosion), atypical hyperplasia of cervical squamous epithelium, carcinoma in situ to invasive cancer for several years, more than ten years or decades. Cervical lesions are easy to find, early diagnosis is not difficult and the radical cure rate is high. Even in the advanced stage, long-term remission can be obtained through active treatment.

Etiology of cervical cancer

The cause of cervical cancer is still unknown. A large number of data at home and abroad confirm that the prevalence rate of women who marry early and have children early, are prolific and have disordered sexual life is high. At present, it is also believed that cholesterol in skin scales can be transformed into carcinogens after bacterial action. It is also an important cause of cervical cancer.

(1) and sexual life and marriage.

The incidence of cervical cancer in women who have sex prematurely (that is, before 18 years old) is four times higher than that in women who have sex after 18 years old. If you start sex too early and suffer from sexually transmitted diseases such as syphilis and gonorrhea, the incidence of cervical cancer is six times higher than that of normal women. It has been proved that if a woman has sex with more than one man, she is more likely to get cervical cancer, while virgins rarely get cervical cancer. Unmarried and parturient women are less likely to get cervical cancer, and the incidence of cervical cancer after multiple marriages is also high. Multiple births and poor perinatal protection and delivery process will also increase the incidence of cervical cancer. But multiple births do not increase the incidence of cervical cancer.

(2) Relationship with spouse

Some people think that the husband's foreskin is too long or phimosis, and the wife's relative risk of cervical cancer is greater. If a man has penis cancer or prostate cancer or his ex-wife has cervical cancer, and a man has multiple sexual partners, his wife's chances of getting cervical cancer will increase.

(3) Virus or fungal infection

Herpes simplex virus type ⅱ, human papillomavirus, human cytomegalovirus and fungal infection may be related to the occurrence of cervical cancer. But which virus is the main cause, or which virus is easy to cause cervical cancer in cooperation, has not been solved.

(4) Cervical erosion, laceration and eversion

Because of its physiological and anatomical structure, the cervix is easily stimulated by various physical, chemical and biological factors, including trauma, hormones and viruses.

(5) People who sit in one place for a long time or don't move for a long time will accumulate toxins, such as mahjong and chess activities and office activities. Prevention of cervical cancer requires more exercise and can be eliminated. This is also the cause of most diseases.

(6) Oral contraceptives will increase the risk of cervical cancer.

Compared with women who have never taken oral contraceptives, the probability of cervical cancer in women who have used oral contraceptives for less than five years is 65,438+00%, while that in women who have used oral contraceptives for five to nine years is 60%. If the service life of oral contraceptives is extended to more than 10 years, the incidence of cervical cancer can be as high as 120%.
