CERVICAL CANCER LÀ GÌ

     

The cervix is part of the female reproductive system, which also includes the fallopian tubes, uterus (womb), ovaries, vagina (birth canal) & vulva (external genitals). 1

The cervix has an outer surface that opens into the vagina and an inner surface that lines the cervical canal. These two surfaces are covered by two types of cells:

Squamous cells – flat, thin cells that cover the outer surface of the cervix (ectocervix). Cancer of the squamous cells is called squamous cell carcinoma. Glandular cells – column-shaped cells that cover the inner surface of the cervix (cervical canal or endocervix). Cancer of the glandular cells is called adenocarcinoma.
