Cervical cancer can spread to pelvic wall, lymph nodes, liver, lungs and other parts of the body through direct spread, lymphatic metastasis and hematogenous metastasis.
1. Direct spread: direct spread is the earliest and most common way of cervical cancer metastasis. It often involves the vaginal wall downward or the main ligaments, paravaginal tissues to the pelvic wall on both sides, seldom involves the uterine cavity upward, and in the advanced stage, it can invade the bladder or rectum in the forward and backward direction.
2. Lymphatic metastasis: if the cancer foci form tumor embolus in lymphatic vessels, the tumor embolus can be transferred to distant lymph nodes through local lymphatic drainage, and can invade lymph nodes in the parietal uterus, pelvis, inguinal area, abdominal aorta and other areas.
3. Hematogenous metastasis: Hematogenous metastasis of cervical cancer is rare, but it can be transferred to lungs, liver and even bones through blood in the late stage.
Early detection of cervical cancer can obviously prolong the survival period, and cervical cancer should be treated in time according to doctor’s prescription to avoid delaying the condition and affecting the prognosis.
