There are no symptoms in the early stage of cervical cancer, and as the disease progresses, patients may experience abnormal vaginal bleeding. Since young women are sexually active, their estrogen level and frequency of sexual intercourse are both higher, so they are more likely to have bleeding during sexual intercourse as the first symptom. In addition, increased leucorrhea is also a common symptom of cervical cancer, and about 80% of cervical cancer patients have this symptom. Clinical follow-up shows that it takes about 10 years to develop from general cervical precancerous lesions to cervical cancer. From this perspective, cervical cancer is not terrible, it is a preventable and curable disease. The key to prevention and treatment is: regular gynecological examination, timely detection and treatment of cervical precancerous lesions and termination of their development to cervical cancer. If prevention and treatment measures are implemented, the cure rate of cervical cancer is very high. In the early stage, it is mostly asymptomatic and not significantly different from chronic cervicitis, sometimes even seen as smooth cervical, especially in elderly women whose cervix has atrophied. When the following symptoms appear, patients should go to regular hospitals for examination and treatment. It is recommended to do TCT+HPV test and colposcopic cervical biopsy if necessary, so as to strive for early detection and early treatment; if it is cervical cancer in situ, cervical cancer can be well cured by cervical conization or total hysterectomy. 1.Vaginal bleeding: Young patients often show contact bleeding, which occurs during sex, gynecological examination and bleeding after stool. The amount of bleeding may be large or small, generally depending on the size of lesion and invasion of interstitial blood vessels. Early bleeding is small, while later lesions are large and may cause fatal hemorrhage once they erode larger blood vessels. Younger 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, 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, a large amount of purulent or rice-soup-like foul-smelling leucorrhea is discharged. 3.Symptoms of advanced cancer: secondary symptoms appear according to the invasion range of lesions. 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.
