What causes cervical cancer

Cervical cancer is mainly related to factors such as human papillomavirus infection, sexual behavior and childbirth factors, low immune function, long-term smoking, and genetic susceptibility. Cervical cancer is one of the common malignant tumors in women. Early detection and treatment can help improve the cure rate.

1. Human papillomavirus infection

Human papillomavirus infection is the main cause of cervical cancer, especially high-risk HPV16 and HPV18. The HPV virus is transmitted through sexual contact and may cause abnormal proliferation of cervical epithelial cells after infection. Long-term persistent infection may lead to cervical intraepithelial neoplasia and eventually cervical cancer. HPV infection can be prevented by vaccination, and regular cervical cancer screening can also detect lesions early.

2. Sexual behavior and childbirth factors

Starting sex too early and having multiple sexual partners increases the risk of HPV infection. Women who have sex for the first time under the age of 16, have multiple sexual partners, or have spouses with multiple sexual partners are more likely to develop cervical cancer. Multiple pregnancies and childbirths can cause damage to the cervix and increase the chance of infection. Women are advised to pay attention to sexual hygiene and avoid early sexual intercourse and multiple sexual partners.

3. Low immune function

People with low immune function are more susceptible to persistent HPV infection. People with AIDS, those who use immunosuppressants after organ transplantation, and those who take long-term glucocorticoids are at increased risk of cervical cancer. The immune systems of these people cannot effectively clear the HPV virus, allowing the infection to persist. It is recommended that people with low immune function undergo regular cervical cancer screening.

4. Long-term smoking

Long-term smoking increases the risk of cervical cancer. Carcinogens in tobacco can reach cervical tissue through blood circulation and damage the DNA of cervical epithelial cells. Smoking also reduces local immunity, making HPV infection more likely to persist. Quitting smoking can help reduce the risk of cervical cancer and improve overall health.

5. Genetic susceptibility

Women with a family history of cervical cancer are at higher risk. Certain genetic variations may affect an individual's immune response to HPV infection and the repair ability of cervical epithelial cells. Although genetic factors cannot be changed, the risk can be reduced through regular screening and preventive measures. It is recommended that women with a family history of cervical cancer should pay more attention to cervical cancer screening.

Preventing cervical cancer requires a comprehensive approach. It is recommended that women of appropriate age receive the HPV vaccine and undergo regular cervical cancer screening. Maintaining a single sex partner and using condoms can reduce the risk of HPV infection. Quitting smoking, limiting alcohol, and maintaining a healthy lifestyle can help strengthen immunity. If you find abnormal vaginal bleeding or discharge, you should seek medical examination promptly. Early-stage cervical cancer is more effective in treating early-stage cervical cancer, and most patients can achieve long-term survival.
