How, then, early detection of cervical cancer?
Cervical cancer is covered by the cervical epithelium and glandular epithelium of malignant tumors. By the epithelial lining occurred mainly squamous cell carcinoma, referred to as squamous cell carcinoma; by the gland epithelium is adenocarcinoma. 5% of cervical cancer occurred in unmarried women were often cervical adenocarcinoma. Cervical cancer is the most common gynecological malignancy of the female reproductive system, more than half of malignant tumors, cancer mortality for women in the first place. Around the age of onset of cervical cancer is different, generally 35-55 years for the cervical carcinoma in situ and invasive for the 40-70 years of age. Statistics show that the incidence of older age. And there is after the extension of the trend. Onset before the age of 20 less. Rural than urban, mountain above the plain.
Cause of cervical cancer has not entirely clear over the past few decades of research and investigation that the incidence of cervical cancer and early marriage, early motherhood, fertility, dense production, multiple marriage, early or frequent sexual disorder, her husband prepuce estrogen secretion disorder or metabolic abnormalities, certain viruses, such as a simple pain-yin E virus and human papilloma virus infection, chronic cervicitis, the cervix and some sexually transmitted health rotten disease. In addition; also immunocompromised patients, poor mental factors and so on.
If we can achieve early detection of cervical cancer, early diagnosis and early treatment the cure rate is relatively high. But not all the early signs of cervical cancer are to detect. In particular, many cases of carcinoma in situ, are to be found in the census. How early detection of cervical cancer? There are some cases of early manifestation of the following should be special attention.
(1) contact bleeding: it may be the only early sign. Refers to the sexual intercourse, gynecological examination, and patients with constipation, hard stool after a small amount of vaginal bleeding. Because of the symptoms can also be found in the cervix and cervical polyps Lian bad, so easily ignored.
(2) irregular vaginal bleeding after menopause: postmenopausal women has been found, bleeding without any pain associated with flu, and thus less likely to arouse the patient attention.
(3) vaginal discharge: more commonly known as vaginal discharge. Can occur in contact bleeding symptoms before or after. The usual emphasis on the color of cervical cancer patients with vaginal leakage of thatched cottages, houses, and a strong stench, but in fact the kind of vaginal discharge is a sign of advanced cervical cancer. The native of early cervical cancer generally not associated with these characteristics.
How early detection of cervical cancer? When patients self-discovery when the early signs should take the initiative to the hospital to find oncology gynecologist or doctor, and do cervical coating (scratch) film examination. This method is simple, diagnostic accuracy is higher. The patient should be noted that in the twenty-four hours before the test ban sexual intercourse to prevent vaginal examination, lavage, and on the drug. Census is the primary means of early detection of cervical cancer. Cervix can be painted (scratch) with the chess pieces cytology test and colposcopy and other methods. Generally over the age of 25 married women, once every three to five years check on the high-risk groups should be checked annually. Cytology suspicious for cancer cases, cervical biopsy should be taken to do biopsy.
