According to the retrospective survey of 29 provinces, cities and autonomous regions, the mortality rate of cervical cancer in China accounts for the fourth place of total cancer mortality and the second place of female cancer. The average age of onset of cervical cancer patients varies from country to country and from region to region, with the age of onset in China being 40-50 years old, with another peak occurring between 60 and 70 years old, and rare before 20 years old. Irregular vaginal bleeding: Early symptoms include a small amount of bloody leucorrhea and contact vaginal bleeding, and patients often come to the clinic because of a small amount of vaginal bleeding after intercourse or defecation. For those who have vaginal bleeding after menopause, attention should be paid to finding the cause. Vaginal bleeding in cervical cancer is often extremely irregular, usually less and then more, sometimes more and sometimes less. Cauliflower type bleeding is early and the amount is also large. In advanced stage, when the cancer erodes large blood vessels, it can cause fatal massive vaginal bleeding. Due to long-term repeated bleeding, patients often develop anemia secondary to it. Pain: It is a symptom of advanced cervical cancer. The cause of pain is mainly due to the infiltration or compression of the pelvic nerves by the cancer. If the closed nerve, sacral nerve, large blood vessels or pelvic wall are involved, it can cause severe pain, sometimes radiating to the lower limbs. Other causes of pain include: pain in the lower abdomen when the cervical canal is obstructed by the cancer and the secretion in the uterine cavity is poorly drained or when pus accumulates in the uterine cavity; pain in the lower abdomen when the cancer invades the parametrium and the ureter is compressed or infiltrated, which can cause ureteral or pelvic ureteral fluid accumulation, resulting in distension or spasmodic severe pain on one or both sides of the lower abdomen; swelling and pain in the lower limbs when the cancer compresses the iliac lymph and iliac vessels, which obstructs the return flow. When the cancer presses the iliac lymph and the iliac vessels block the return flow, swelling and pain of lower limbs may appear. 3.Increased vaginal discharge: Most patients with cervical cancer have increased vaginal discharge in different degrees. In the initial stage, due to the hyper-secretory function of cervical glands stimulated by cancer, mucus-like leucorrhea is produced. With the development of cancer tumor, necrosis and shedding of cancer tissues and secondary infection, leucorrhea becomes cloudy, such as rice water-like or pus-like with blood, and has special foul smell. 4.Other symptoms: When advanced cervical cancer invades the bladder, it may cause frequent urination, painful urination or hematuria, and even vesicovaginal fistula. If both ureters are blocked by pressure, it can cause urinary closure and uremia, which is one of the main causes of death. When the cancer spreads backward and presses or invades the rectum, there is often urgency, blood in stool or difficulty in defecation, and even formation of rectovaginal fistula. The metastatic symptoms of cervical cancer can invade the bladder when the cancer spreads to the front. Patients with advanced symptoms of cervical cancer have frequent urination, urgent urination, painful urination, falling and hematuria, which are often misdiagnosed as urinary tract infection and delay the diagnosis. In severe cases, vesico-vaginal fistula can be formed. If the cancer spreads backward, it can invade the rectum, and there are symptoms such as cramping, difficulty in defecation, urgency and blood in the stool, etc. Further development can lead to vaginal-rectal fistula. Distant metastasis may occur in the advanced stage of the disease. The more common is supraclavicular lymph node metastasis, in which nodes or masses appear. Cancer infiltration can spread to distant organs through blood vessels or lymphatic system and metastases can appear in the corresponding areas with corresponding symptoms.
