Cervical cancer refers to a malignant tumor that occurs in the vaginal part of the uterus and the cervical canal. The metastasis of cervical cancer can spread directly to adjacent tissues and organs, downward to the vaginal vault and vaginal wall, upward to the uterine body, to the sides to invade the pelvic tissue, forward to invade the bladder, and backward to invade the rectum. It can also metastasize to the paracervical, internal iliac, external iliac, and inguinal lymph nodes through lymphatic vessels, and even to the supraclavicular and other lymph nodes throughout the body in the late stage. Generally speaking, cervical cancer can be cured, especially in early cases, whether surgery or radiotherapy, the effect is good? The annual survival rate is about 95%. The treatment effect of advanced cases is poor. If surgery, radiotherapy, chemotherapy and other comprehensive treatment methods are properly selected, there are also cases of cure. Even if it cannot be cured, if the development of cancer can be temporarily inhibited or delayed, the patient's quality of life and survival period can be improved. Cervical precancerous lesions refer to lesions that occur in the area before cancer occurs, which lead to cancer. In the late stage, radiotherapy and chemotherapy are mainly needed, and Chinese medicine is needed as an auxiliary treatment. The main purpose is to prolong the time and improve the quality of life. Severe cervical intraepithelial neoplasia is a precancerous lesion. It is reversible, that is, part of the lesion can disappear naturally, but it is also progressive, that is, the lesion can develop and even become cancerous. Its reversibility and progression are related to the scope and degree of the lesion. The possibility of mild intraepithelial neoplasia disappearing naturally is significantly greater than that of moderate and severe intraepithelial neoplasia. The possibility of severe intraepithelial neoplasia developing into cancer is significantly greater than that of mild and moderate intraepithelial neoplasia. Some scholars also believe that mild cervical intraepithelial neoplasia is a benign abnormal proliferation that can naturally turn to normal. |
