Cervical cancer is something that family members and friends do not want to see no matter which woman it happens to. If female friends must consider for their own health, they should do prevention and regular checkups in advance, and if it is detected, the chance of cure will be very high. Because the early symptoms of cervical cancer are not obvious, it is usually found in the middle to late stage, which is difficult to treat. I. Early symptoms of cervical cancer. 1. Contact bleeding: This is the most prominent symptom of cervical cancer, about 70%-80% of patients with cervical cancer have vaginal bleeding. It is mostly manifested as vaginal discharge mixed with fresh blood after sexual intercourse or gynecological examination, or during forceful bowel movement. If older women experience bleeding after sex, they should not always think that it is caused by improper sexual intercourse and ignore the possibility of cervical cancer. If there is bleeding after sex every time, you should pay attention to it and seek medical attention in time. Irregular vaginal bleeding: Older women have been menopausal for many years, but suddenly “come on” again without any reason. The amount of bleeding is often small and is not accompanied by symptoms such as abdominal pain and back pain, so it is easy to be ignored. In fact, this kind of irregular vaginal bleeding is often an early sign of cervical cancer, and many elderly patients come to the clinic with this symptom to get early diagnosis and timely treatment. Therefore, it should be highly alert to the elderly. 3.Increased vaginal discharge: Clinically, about 75%-85% of patients with cervical cancer have increased vaginal discharge to different degrees. Most of them are increased leukorrhea, which is later accompanied by changes in smell and color. The increase of leucorrhea is due to the stimulation of cancerous tumor. Initially, it has normal color and odor, but later, due to necrosis of cancerous tissues with infection, purulent, rice-soup-like or bloody leucorrhea with foul odor will flow from vagina. 4.Metastatic symptoms of cervical cancer: Besides lymphatic metastasis, lung metastasis, liver metastasis and bone metastasis are more common, and the corresponding symptoms appear. 5. Systemic symptoms: In addition to systemic symptoms such as uremia, patients with cervical cancer often show clinical manifestations such as emaciation, anemia, fever, systemic failure and cachexia in late stage. 2. Methods of preventing cervical cancer. 1.Regular examination: Cancer does not occur overnight, but has a gradual evolution process. Therefore, through regular screening, some precancerous lesions and asymptomatic cancers can be detected and then given active treatment. 2.Keep a sterile living environment: Keep a sterile living environment, and women who have sex should keep clean and fresh bed sheets. 3.
