CERVICAL CANCER

Cervical cancer development process in recent years, by a large number of studies have clearly precancerous lesion is atypical hyperplasia, dysplasia, carcinoma in situ and invasive cervical cancer as a group of diseases continuity; Early lesions from the surface of atypical hyperplasia, causes continue to exist, it will gradually progress to invasive carcinoma.

The study also proved that the vast majority of cervical cancer is gradual rather than sudden, a precancerous lesion often for a very long time is reversible, then entered the surface "carcinoma in situ" stage, this period is sustainable for many years, in this period of no clinical symptoms, the availability of the cervical carotid cells scratch-ray examinations found, and the needle biopsy method that diagnosis.

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.
