Cervical cancer is a disease in which cancer cells grow in the cervix. The cervix is the lower, narrow part of the uterus (womb) that connects the uterus with the vagina.
Cancer occurs when cells in the body (in this case, epithelial cervix cells lining the cervical canal) divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant tumors, which can invade nearby tissue and spread to other parts of the body. A benign tumor does not invade or spread.
