Cervical cancer originates from the cervix and may spread to the surrounding tissues such as vaginal wall, main ligament, and may also metastasize to the lymph nodes next to the uterus, and even have distant metastasis. Cervical cancer is the most common gynecological malignant tumor, which originates from the cervix and may grow outward in the form of cauliflower, brittle and easy to bleed; it may also infiltrate into the deep tissues of the cervix; it may be combined with infection and necrosis in the form of ulcer. With the development of cervical cancer, the scope of involved tissues expands. It can directly spread to the surrounding organs and tissues, such as involving the vaginal wall downward, invading the main ligament and the cervix, the paravaginal tissues and even the pelvic wall on both sides, and invading the anterior bladder and the posterior rectum in the late stage. Cervical cancer can also invade peripheral lymph nodes such as paracervical, obturator, internal iliac and external iliac lymph nodes via lymphatic metastasis; although distant metastasis is uncommon, cervical cancer can also be metastasized to the lungs, liver, bones and other parts of the body via blood line.
