Cervical cancer, the tumor “killer”, has long been a nightmare for female patients. According to statistics, there are about 466,000 new cases of cervical cancer worldwide every year, 80% of which occur in developing countries. Cervical cancer is one of the most common cancers in human body, which not only takes the first place among female genital tumors, but also is the most common cancer among various malignant tumors in women. Symptoms of cervical cancer 1. Early stage of cervical cancer is mostly asymptomatic, and there is no obvious difference with chronic cervicitis, sometimes even smooth cervix, especially in elderly women who have atrophied cervix. (1) Vaginal bleeding: Young patients often show contact bleeding, which occurs during sex, gynecological examination and after stool. The amount of bleeding may be large or small, depending on the size of the lesion and the invasion of the interstitial vessels. Early bleeding is small, while later lesions are large and may cause fatal hemorrhage once they erode larger blood vessels. Young patients may also present with prolonged periods, shortened cycles, and increased menstrual flow. Older patients often complain of irregular vaginal bleeding after menopause. (2) Vaginal discharge: Patients often complain of increased vaginal discharge, which is white or bloody, thin like watery or rice soup-like, with fishy odor. In late stage, due to the rupture of cancer tissue, tissue necrosis and secondary infection, there is a large amount of purulent or rice-soup-like foul-smelling leucorrhea discharge. 2.Symptoms of advanced cancer: secondary symptoms appear according to the extent of lesion invasion. When the lesion spreads to connective tissue of pelvic cavity, pelvic wall, compressing ureter or rectum or sciatic nerve, patients often complain of frequent urination, urgent urination, anal swelling, constipation, shortness of breath, swelling and pain of lower limbs, etc. In serious cases, it leads to ureteral obstruction and hydronephrosis, and finally causes uremia. At the end of the disease, patients may develop emaciation, anemia, fever and general failure.
