Cervical cancer is clinically known as cervical cancer. Early cervical cancer has no obvious symptoms and signs. Those in middle and late stages or with symptoms may show the following aspects: 1. Vaginal bleeding: it often manifests as contact bleeding, i.e. vaginal bleeding after sexual intercourse or gynecological examination. It may also manifest as irregular vaginal bleeding, or prolonged menstrual period and increased menstrual flow. Elderly patients often have postmenopausal irregular vaginal bleeding. The amount of bleeding varies according to the size of the lesion and the encroachment of interstitial blood vessels, and may cause hemorrhage if large blood vessels are encroached upon. Generally speaking, bleeding of exogenous type of cancer (cancer foci growing outward) is earlier and more abundant; bleeding of endogenous type of cancer (cancer foci invading into deep tissues of uterine cervix) is later. Vaginal discharge: most patients have white or bloody, thin watery or rice slop-like vaginal discharge with fishy odor. Due to the necrosis of cancerous tissues and infection in late-stage patients, there may be a large amount of rice slop or purulent smelly leukorrhea. 3. Late stage symptoms: according to the range of involvement of cancerous foci, there are different secondary symptoms, such as frequent urination, urgency of urination, constipation, swelling and pain of lower limbs, etc. When cancerous tumor oppresses or involves ureter, it can cause ureteral obstruction, pyelonephrosis and uremia; and there can be systemic exhaustion symptoms, such as anemia and cachexia, etc. in the late stage. Therefore, early stage of cervical cancer is asymptomatic, and those who have symptoms are mainly contact vaginal bleeding and bloody leukorrhea. In the late stage, the tumor may erode the tissues and there may be massive vaginal bleeding, and there may be malodor when the tissues decay and necrotic, and there may be corresponding symptoms when it invades the neighboring organs and nerves.
