Overview of cervical cancer
Cancer occurs when cells in the body start to grow out of control. Cervical cancer is when cancer cells start in the cervix — the lowest part of the uterus that attaches to the vagina.
The cervix is made up of two different kinds of cells: glandular cells that form the body of the uterus (called the endocervix) and squamous cells that form the bottom part of the cervix (called the exocervix). The place where the two types of cells meet — the transformation zone — is where most cervical cancers begin.
