With the accelerated pace of life, the common “health killer” of women is not only breast cancer, but also cervical cancer, which is second only to breast cancer in terms of incidence. What’s more, the age of onset of cervical cancer has advanced from the 50s to the 30s. Early prevention of cervical cancer is a matter of urgency. Most of the cervical cancers have the process of developing from “inflammation” to “cancer”. Therefore, women should pay extra attention to the following symptoms when they appear: contact bleeding: vaginal discharge (leukorrhea) mixed with drops of fresh blood after sexual intercourse or constipation, sometimes in the form of streaks, sometimes in dark red. The sudden appearance of vaginal bleeding after intercourse in women over 30 years old who have already given birth and live together should be taken seriously as an early sign of cervical cancer. Irregular vaginal bleeding is manifested as non-menstrual small amount of vaginal bleeding between menstrual periods and post-menopausal vaginal bleeding. The former is easily regarded as irregular menstruation and the latter is easily regarded as menopausal manifestation. However, such irregular vaginal bleeding is indeed seen in the early stages of cervical cancer and is the first symptom of the patient. Abnormal vaginal discharge Mostly manifests as increased leukorrhea with changes in color and odor. The symptoms of increased leucorrhea usually appear later than contact bleeding, which is normal in color and odor at the beginning and gradually changes to plasma discharge, and rice slop-like or watery leucorrhea may be seen in advanced cervical cancer. Recommendation: women should be screened for cervical cancer at 21 years old Cervical cancer is a malignant tumor with clear etiology and pathogenesis, and it is also a malignant tumor that can be easily prevented early through regular checkups. The most effective cervical cancer screening techniques used internationally are cervical fluid-based thin-layer cytology (TCT) and high-risk HPV testing, and with the younger incidence of cervical cancer, all women should start cervical cancer screening at the age of 21. Women aged 30 to 65 should be tested for both cervical TCT and HPV every 3 years.
