Cervical Cancer Stage 1
In stage 1, cancer is present only in the cervix. Stage I is divided into stages 1A and 1B, based on the amount of cancer that is found.

• Stage 1A : A very small amount of cancer that can only be seen with a microscope is found in the tissues of the cervix. The cancer is not deeper than 5 millimeters and not wider than 7 millimeters.
• Stage 1B : In stage 1B, cancer is still within the cervix and either:
• Can only be seen with a microscope and is deeper than 5 millimeters or wider than 7 millimeters; or
• Can be seen without a microscope and may be larger than 4 centimeters.
