• Women over 25 years old should undergo regular TCT+HPV combined screening
• Even if you have received the HPV vaccine, you still need regular check-ups
• Biopsy is the gold standard for diagnosis, so don’t be overly afraid
If you have abnormal symptoms or abnormal screening, please go to the gynecology department of a regular hospital in time to avoid trusting non-professional advice on the Internet. Cervical lesions progress slowly, and the cure rate with early intervention can reach 100%.
