The main symptoms of cervical cancer are vaginal bleeding, increased vaginal discharge and pain, etc. The form and degree of its manifestation are related to the early and late stage of cervical cancer lesion and pathological type. The specific manifestations are as follows: 1. Increased vaginal discharge Most cervical cancer patients have increased vaginal discharge in different degrees. In the early stage, due to the hyper-secretory function of cervical glands stimulated by the presence of 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 odor. 2.Irregular vaginal bleeding The early manifestation is 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 sexual 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 the long-term repeated bleeding, patients often develop anemia secondary to it. Pain is a symptom of advanced cervical cancer. The reason for pain is mainly due to the infiltration or compression of pelvic nerves by 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 pain-causing causes include pain in the lower abdomen when the cervical canal is obstructed by cancer tumor, poor drainage of uterine secretion or formation of pus in the uterine cavity; when the cancer invades the parametrial tissues and the ureter is compressed or infiltrated, it may cause ureteral or pelvic ureteral fluid accumulation, resulting in distension or spasmodic severe pain on one or both sides of the lower abdomen; when the cancer compresses the iliac lymph and iliac vessels and obstructs the return flow, swelling and pain in the lower limbs may occur. 4.Other symptoms When advanced cervical cancer invades the bladder, it may cause frequent urination, painful urination or hematuria, and even vesicovaginal fistula may occur. 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, it often causes urgency, blood in stool or difficulty in defecation, and even forms rectovaginal fistula.
