Cervical cancer is currently the only malignant tumor in the world whose cause is known, so it is also the only malignant tumor that can be screened for or diagnosed early before it develops. Because of this, the incidence rate of cervical cancer is decreasing year by year, so we have reasons and opportunities to make ourselves well-cared for and try our best to do screening or early diagnosis and treatment after suffering from this disease. 1.Cervical cancer screening should start from women over 21 years old, or under 21 years old who have started their sexual life for more than 3 years. 2.Women in the age group of 21-29 years should be screened every two years. 3. For women over 30 years of age, if they do not have CIN 2 or CIN 3, are not HIV-infected, are not in an immunosuppressed state, have no history of estrogen use, and have three consecutive normal screening results, the interval of screening can be changed to every three years. 4. For women over 30 years old, the best screening method is to perform both cytology screening TCT and HPV testing, and if both results are normal and belong to the low-risk group for cervical cancer, the screening interval should preferably be more than three years.
