What causes cervical cancer

Cervical cancer is a malignant tumor that originates in the cervix of the uterus and may be related to high-risk human papillomavirus infection, unhealthy sexual behavior, cervical injury, long-term use of contraceptives, and other factors.

1. High-risk human papillomavirus infection: This is the main cause of cervical cancer, especially high-risk human papillomavirus infection, such as types 16 and 18. These viruses are transmitted through sexual contact, infect cervical epithelial cells, and cause cancer in cells and surrounding tissues.

2. Unhealthy sexual behavior: Starting sexual life too early, such as first sexual life before the age of 16 and having multiple sexual partners, will increase the risk of HPV infection, thereby increasing the incidence of cervical cancer. At the same time, unclean sexual behavior is also prone to infection with various pathogens, such as herpes simplex virus type 2, Chlamydia trachomatis, Trichomonas, etc. These pathogens have a synergistic effect in the onset of cervical cancer.

3. Cervical damage: Poor menstrual hygiene, prolonged menstruation, early marriage, early childbearing, multiple births and other factors may cause damage to the cervix and increase the risk of cervical cancer. At the same time, multiple miscarriages or childbirth may also cause damage to the cervix and increase the risk of cervical cancer.

4. Long-term use of contraceptives: Long-term use of oral contraceptives may cause endocrine disorders and increase the risk of cervical cancer. At the same time, long-term use of immunosuppressive drugs after organ transplantation will also reduce the body's immunity and increase the incidence of cervical cancer.

5. Other factors: Malnutrition, poor sanitation, poor socioeconomic conditions, etc. may also increase the incidence of cervical cancer. At the same time, long-term stimulation of chronic inflammation of the cervix or frequent trauma caused by sexual violence can also lead to an increased risk of reproductive tract infection and cancer.

Note: In order to prevent the occurrence of cervical cancer, it is recommended that women get the HPV vaccine before having sexual intercourse, and at the same time pay attention to personal hygiene, avoid unclean sexual behavior, maintain good living habits and a balanced nutritional intake.
