Some info that will help you prevent cervical cancer. Definition - Anatomically the uterus and vagina are joined together by the neck. The surface of the cervix consists of an epithelium that is to say roughly two cell layers (superficial and deep separated by what is known as histology (study of cells) a basal lamina. The process of the cancer cell layers may occur, it is a question of epithelioma.



Sometimes the basal lamina is not affected. In this case it is only the epithelial cells that are modified surface. This is called d 'Epithelioma intraepithelial, epithelial nvasif or pre-cancer stage 0 (carcinoma in situ of specialists). When the basal lamina is exceeded the connective tissue located below is reached, it is in this case of invasive cancer . Between the outer cervix is called the ectocervix and interior: the endocervix, the branch is fragile and often place of carcinogenesis also.

Symptoms
In some cases there are no symptoms. Through systematic examination of the neck for a gynecological checkup or under medical supervision of a woman who had a history such as polyps, ulcers or other, the identification of cervical cancer of the uterus is possible. In all other cases the patient presents the following signs:

* Loss of blood called bleeding usually caused by sexual intercourse or intimate toilet
* Leucorrhœa that is to say, vaginal discharge that is painless

Medical tests
These are the cervical (removal of cells of the cervix uteri using a special brush) sometimes associated with colposcopy (direct visualization of the cervix after insertion of a vaginal speculum) which allows biopsy c that is to say, the removal of the mucosa (layer of cells covering the cervix) suspicious of cancer. The Bethesda classification includes: Quality of levy 1) Satisfactory for evaluation 2) Satisfactory for evaluation but limited for some reason it should be noted. 3) Unsatisfactory for evaluation (give reason) Diagnosis

* The smear is normal: it presents benign cellular changes due to infection (herpes, trichomoniasis, mycosis, actinomycosis) or because of inflammatory changes, secondary to the insertion of an IUD or radiation among others.
* The smear shows abnormal epithelial cells (cells lining the inside of the uterus) because there is the presence of Malpighian cells (cell type of the mucous cell lining of the uterus). The abnormal epithelial cells has 4 types:
A) the cell type Malpighian whose meaning is not accurately determined (ASCUS) B) the lesion squamous epithelial low grade, which includes HPV (infection with human papilloma virus) and potentially cancer requiring consideration of sexual partner, mild dysplasia (slight modification of cells) and CIN 1.

The CIN 1 is the presence of condyloma (small skin tumors that sits on the genitals and anus). C) lesion of the Malpighian cells of grade 2 with a moderate to severe changes of these cells (CIN 2, CIN 3) D) Squamous cell Malpighi: the term covers 80% of cancers. A carcinoma is a malignant (cancerous) that grows at the expense of coating tissue, like skin or mucous membranes. Abnormalities of glandular cells (cells that secrete products) are of two types: A) abnormalities not typical of cells of these glands whose meaning is known (AGUS) adenocarcinoma (glandular cancer) of which must specify the site: endocervical (inside the neck of the uterus), endometrial (at 'inside the uterus itself), extra-uterine (outside the uterus), unspecified.
