Severe cervical erosion can lead to cancer within a few years

Severe cervical erosion itself is not a precancerous lesion, but long-term untreated cervical erosion combined with persistent high-risk HPV infection may increase the risk of cervical cancer. The occurrence of cervical cancer usually takes 5-10 years or even longer, and is mainly related to factors such as HPV infection and immune status.

Cervical erosion is the physiological phenomenon of cervical columnar epithelial migration, which is medically called cervical columnar epithelial ectopia. Severe erosion refers to the ectopic range exceeding two-thirds of the cervical area, and the probability of cancer is directly related to whether it is combined with high-risk HPV infection. Simple erosion will not directly lead to cancer, but the erosion surface may increase the risk of HPV infection. If persistently infected with high-risk HPV types 16 or 18, some patients may progress to cervical intraepithelial neoplasia and eventually invasive cancer within 5 to 10 years. Clinical data shows that it takes an average of 10-15 years from HPV infection to cancer, but individual differences are large.

In rare cases, if the patient has immune deficiency, long-term smoking, or a history of multiple childbirths, the progression of the disease may be accelerated. For patients who are infected with HIV or who use immunosuppressants after organ transplantation, the time to cancer may be shortened to 3-5 years. However, in this case, multiple conditions such as persistent high-risk HPV infection and abnormal cervical cytology must be met at the same time. Simple erosion will not lead to rapid canceration.

It is recommended that combined cervical TCT and HPV screening be performed every year, and colposcopy biopsy should be performed promptly if abnormalities are found. Maintaining a single sexual partner, getting the HPV vaccine, and avoiding smoking can significantly reduce the risk. If contact bleeding or abnormal secretions occur, you should seek medical treatment as soon as possible. Physical treatments such as laser and cryotherapy can effectively improve the symptoms of erosion.
