Cervical cancer is the most common gynecological malignancy. The high incidence age of in situ cancer is 30 to 35 years old, and that of invasive cancer is 45 to 55 years old; in recent years, there is a trend of its incidence becoming younger. The common application of cervical cytology screening in recent decades has enabled early detection and treatment of cervical cancer and precancerous lesions, and the incidence and mortality rate of cervical cancer have been significantly reduced. Then, what are the high-risk factors of cervical cancer? The following are the high-risk factors of cervical cancer. 1. Personal hygiene, sexual hygiene and menstrual hygiene Underwear, underpants, toilets and washing machines should be cleaned and disinfected regularly. In addition, sexual hygiene is also very important, especially bathing before sex to keep the external genitalia clean to avoid bringing bacteria and viruses into the deep vagina through sexual intercourse and causing infection. Avoid sexual intercourse during menstruation. 2.First sexual intercourse and sexual partners Some information shows that the earlier the age of first sexual intercourse, the higher the rate of cervical cancer. The risk of cervical cancer for women who have sex at the age of 22 or above is set at 1, then the risk of cervical cancer for women who have sex at the age of 20-21 increases to 1.62; if they have sex at the age of 18-19, the risk increases to 2.54; if they have sex at the age of 16-17, the risk of cervical cancer increases to 1.62. The risk of cervical cancer increases to 3.88 if you have sex at the age of 16-17, which tells us that the earlier you have sex, the more dangerous it is for women. At that time, women’s reproductive system and cervix are not yet mature, and their ability to resist foreign invasion and disease is also very low, so they are easily hurt and infected, which will lead to cervical cancer in the future. The more sex you have, the higher the risk of cervical cancer. 3, contraceptive pills The cervix has a special “migratory zone”, which is a good site for cervical cancer, and research has found that oral contraceptive pills may affect the changes in this migratory zone, thus becoming a reason for our attention. What is the best method of contraception? It is generally believed that what suits you is the best. Here we recommend condoms, both for men and for women. 4.Healthcare during childbirth, pre-pregnancy and lactation Health care during pregnancy, childbirth, puerperium and lactation is also closely related to the incidence of cervical cancer. The earlier, denser and more children are born, the worse the health care is done in each period, the higher the incidence of cervical cancer will be. 5.Smoking There is a certain relationship between smoking and the occurrence of cervical cancer because scientists have detected harmful substances in tobacco in the mucus of the cervical canal, such as nicotine, cyanide and other toxic and harmful substances in tobacco will play a synergistic role with the virus. 6.Male related factors The development of cervical cancer is closely related to men. The male foreskin folds and coronal sulcus are prone to accumulate some dirt, in which there are many bacteria and viruses. It has also been shown that if a man’s ex-wife died of cervical cancer, his partner’s risk of developing cervical cancer is 2-3 times higher than normal. The risk of STDs and penile cancer is also increased when men have more sexual partners. Therefore, for the sake of their families and their wives, men should also pay attention to personal hygiene, sexual hygiene and abide by sexual morality.
