CERVICAL CANCER

Transfer way: As the cervical epithelium and the lack of lymphatic vessels, is the organization of the basement membrane barriers to prevent invasive cancer, carcinoma in situ is not a transfer, carcinoma in situ into invasive cervical cancer, the cancer could spread, the main channel for the transfer:

1) direct spread: spread to the vagina, cervix, often endogenous tumor spread downwards, the first infiltration vaginal fornix, to the vagina, under paragraph expansion of cervical lesions in the neck of the expansion, thickening and hardening, and involved the spread of intrauterine, penetrating Palace wall, in the proliferation of celiac . Beside organizations to the spread of bilateral main ligaments and sacral ligament, the entire pelvic tumor formation hard, in a "frozen pelvis." Uterine cancer invasion may oppression or a bilateral ureter, which ureteral obstruction. The bladder and rectum violations, can cause hematuria, "moderate" flu.

2) lymphatic metastasis: interstitial infiltration to cervical cancer can be invasive lymphatic tumor thrombus formation, with the nearby lymph flow of lymph nodes in the lymphatic spread. Its transfer channels: 1 cervical lesions basement lymphatic → beside an obturator lymph node → iliac lymph node areas inside and outside the common iliac lymph nodes → District para-aortic lymph node → supraclavicular lymph nodes → Waterloo lymph nodes. ② cervical lesions lymphatic → presacral → aortic lymph nodes under the lymph nodes.

3) hematogenous metastasis: differentiation seen in the advanced or poor patients, may spread to the lung, liver, kidney, bone, brain, skin and other parts.
