Cervical cancer: malignant cancer of Cervix Uteri or cervical area. It may present with vaginal bleeding but symptoms may be absent until the cancer is in its advanced stages, which has cancer of the neck of the focus efforts screening intensive Word orders. In developed countries the prevalence of cervical screening programs has reduced the incidence of invasive cervical cancer by 50% or more.
Cervix is the lower part of uterus (womb). It is sometimes called the uterus neck. Unit (upper part) of the uterus, is where there is a growing embryo. The body of the uterus neck connects the Vagina (birth canal). Part closest to the body of the uterus neck called the endocervix. Part next to the Vagina is exocervix (or ectocervix). The place where these comply with part 2 is the name of the zone of transition. The majority of cervical cancer begin the transformation zone.
Approximately 85% of cervical cancer are squamous cell carcinomas, which develop in the flat, scaly, covering with cervix skinlike cells. Most of the other cervical cancer are adenocarcinomas, which develop from the gland cells, adenosquamous carcinomas or that develop from a combination of types of cells.
Symptoms of cervical cancer

The cause of cervical cancer
Cervical cancer begins in thin, flat cells that line the bottom of the neck (squamous cells). Squamous cell carcinomas account for about 80 percent of cervical cancer. Cervical cancer can also occur in cells gruczolowa that line the top of the neck.
Genetic material, which originates from certain forms of HPV has been found in cervical tissue, which show the changes of the bronchi or precancerous.

More than 90 percent of all cervical cancer are squamous cell carcinomas, and researchers believe that the cancer may be diseases transmitted sexually. There is ample evidence that cervical cancer is associated with sexually transmitted infections of organisms.
Chemical exposure: women who work on farms or in the manufacturing industry is likely to be exposed to chemical substances that may increase the risk of cervical cancer.
Women who have HIV, the virus that causes AIDS, often to take drugs which weaken the body's natural immunity or his ability to fight off disease. These women were also increased the risk of cervical cancer and should be closely monitored by their gynaecologist for the development of precancerous changes in the cervix.
