The causes of cervical cancer are still unclear. A lot of data from home and abroad confirm that women with early marriage, early childbearing, multiple births and disordered sexual life have a higher prevalence. It is also believed that the cholesterol in circumcision can be transformed into carcinogenic substances after the action of bacteria. It is also an important cause of cervical cancer, and the specific factors are as follows: 1. Relationship with sexual life and marriage Women who have early sexual life (meaning having sex before the age of 18) have a 4 times higher incidence of cervical cancer than those who start to have sex after the age of 18. The incidence of cervical cancer is six times higher in women who start sex early and have sexually transmitted diseases such as syphilis and gonorrhea than in normal women. It has been proven that women who have sex with more than one man have more chances of developing cervical cancer, while virgins rarely develop cervical cancer. Unmarried and unborn women have very little chance of developing cervical cancer, and the incidence of cervical cancer is also higher in multiple marriages. Multiple births with poor perinatal protection and delivery procedures can also increase the incidence of cervical cancer. However, multiple births do not increase the incidence of cervical cancer. Relationship with spouse It is believed that the relative risk of cervical cancer in the wife of a husband who is circumcised or circumcised is higher. If a man has penile cancer or prostate cancer or his ex-wife has cervical cancer, and if a man has multiple sexual partners, his wife has a higher chance of cervical cancer. Herpes simplex virus type II, human papilloma virus, human cytomegalovirus and fungal infections may be related to the occurrence of cervical cancer. However, the question of which virus is the main trigger or which kinds of viruses are likely to occur in concert with cervical cancer has not been solved. 4.Cervical erosion, laceration and ectropion Due to the physiology and anatomy of the cervix, it is susceptible to various physical, chemical and biological stimuli, including trauma, hormones and viruses. 5. Those who remain immobile for a long time will accumulate toxins For example: mahjong activities, office activities, etc. The prevention of cervical cancer can be eliminated if you need to exercise more. This is also the cause of most of the morbidity. 6.Oral contraceptives can increase the risk of cervical cancer Compared with women who never take oral contraceptives, those who use oral contraceptives for less than 5 years have a 10% chance of cervical cancer, while women who have used oral contraceptives for 5 to 9 years have a 60% chance of cervical cancer, and if the use of oral contraceptives is extended to more than 10 years, the incidence of cervical cancer can be as high as 120 The incidence of cervical cancer can be as high as 120% if oral contraceptive use is extended beyond 10 years.
