The successive deaths of actresses Anita Mui and Yuan Yuan Li brought the disease of cervical cancer to the public. In fact, cervical cancer is the most easily preventable malignant tumor at present. As long as effective preventive measures are taken, women can completely avoid the recurrence of tragedies. The most effective measure to prevent cervical cancer – regular cervical exfoliation cytology examination, commonly known as cervical cancer screening or cervical smear, or cervical TCT – takes 5-10 years to develop and form, so any cytology examination during this period can help detect the lesion early, thus guiding the doctor to take effective measures to stop the formation of cancer completely. Experts from the World Health Organization and the Chinese Society of Obstetrics and Gynecology recommend that women over the age of 18 who are sexually active should undergo cervical cancer screening once a year.
