Cervical Cancer

The cervix is part of a woman’s reproductive system. The cervix is the lower, narrow part of the uterus (womb). The cervix connects the uterus to the vagina. The cervix makes mucus. During pregnancy, the cervix is tightly closed to help keep the baby inside the uterus. During childbirth, the cervix opens to allow the baby to pass through the vagina.
Cervical cancer forms in the interior lining of the cervix, the junction of the vagina and uterus. Most cervical cancers begin in the cells lining the cervix. These cells do not suddenly change into cancer. Cervical cancer is almost always caused by human papillomavirus (HPV) infection. The virus spreads through sexual contact. Most women’s bodies are able to fight HPV infection. But sometimes the virus leads to cancer.
The development of cervical cancer is typically slow, and occurs over a period of years.Cervical cancer is most often diagnosed in middle-aged women, with half of those diagnosed between the ages of 35 and 55.

Types of Cervical Cancer

There are two types of cervical cancer :
– Squamous cell carcinoma : These cancers are from the squamous cells that cover the surface of the exocervix. Under the microscope, this type of cancer is made up of cells that are like squamous cells. Squamous cell carcinomas most often begin where the exocervix joins the endocervix.
– Adenocarcinoma : This develops mucus-producing glandular cells of the endocervix, the part of the cervix next to the body.
