What are the main types of cervical cancer?

The two main types of cervical cancer are squamous cell carcinoma and adenocarcinoma. Cervical cancers are named after the type of cell where the cancer started.

Up to 90% of cervical cancers are squamous cell carcinomas. These develop from cells in the ectocervix, the outer part of the cervix. Adenocarcinomas develop in the glandular cells of the endocervix, the inner part of the cervix.

Sometimes cervical cancer has features of both types, which is called mixed carcinoma or adenosquamous carcinoma. Very rarely, cancer develops in other cells in the cervix. Your healthcare team can explain more about the type of cervical cancer in your situation.
