Early diagnosis method of cervical cancer How to treat early cervical cancer

In developed countries, the incidence of cervical cancer has dropped significantly due to early diagnosis and treatment. In developing countries, due to imperfect cervical screening, the incidence of cervical cancer is 6 times that of developed countries.

According to clinical follow-up observations, it takes about 10 years for general cervical precancerous lesions to develop into cervical cancer. From this perspective, cervical cancer is not terrible, it is a disease that can be prevented and cured. The key to prevention and treatment is to conduct regular gynecological examinations, timely detect and treat cervical precancerous lesions, and end the development of cervical cancer. If prevention and control measures can be implemented, the cure rate of cervical cancer is very high.

The diagnosis of cervical cancer is mainly based on medical history and clinical manifestations, especially contact bleeding, which requires a detailed systemic examination and gynecological diagnostic examination, and uses cervical scraping cytology, iodine test, nitrogen laser tumor intrinsic fluorescence diagnosis, colposcopy, cervical and endocervical canal biopsy, cervical conization, etc. After the diagnosis of cervical cancer, chest examination, X-ray photography, lymphangiography, cystoscopy, proctoscopy, etc. should be performed according to the specific situation to determine the clinical stage.

There are no symptoms in the early stage, and there is no obvious difference from chronic cervicitis. Sometimes the cervix is ​​even smooth, especially in elderly women. The main symptoms are:

Vaginal discharge: Patients often complain of increased vaginal discharge, which is white or bloody, thin like water or rice soup, and has a fishy smell. In the late stage, due to rupture of cancer tissue, tissue necrosis, secondary infection, etc., a large amount of pus or rice soup-smelling leucorrhea is discharged.

Vaginal bleeding: Young patients often present with contact bleeding, which occurs during sexual intercourse, gynecological examinations, and after bowel movements. The amount of bleeding can be more or less, generally depending on the size of the lesion and the invasion of blood vessels in the stroma. Early bleeding is less, while late lesions are larger and present with heavy bleeding, which may lead to fatal heavy bleeding once they erode large blood vessels. Young patients may also present with prolonged menstruation, shortened cycles, and increased menstrual flow. Elderly patients often complain of irregular vaginal bleeding after menopause.

Symptoms of advanced cancer: secondary symptoms appear according to the extent of the lesion invasion. When the lesion affects the pelvic connective tissue, pelvic wall, compresses the ureter or rectum, sciatic nerve, frequent urination, urgency, anal swelling, constipation, urgency, lower limb swelling and pain, etc., severe lead to ureteral obstruction, hydronephrosis, and eventually lead to uremia. At the end of the disease, the patient may experience weight loss, anemia, fever and systemic failure.
