Stage I cervical cancer
In stage I cervical cancer, the cancer has grown deeper into the cervix, but has not spread beyond it. This stage is further separated into two subcategories:
- Stage IA: There is a very small amount of cancer, less than 5 mm deep and less than 7 mm wide, that can only be seen under a microscope.
- Stage IB: The cancer can be seen and measures 4 cm or less; or the cancer can only be seen under a microscope and measures more than 5 mm deep and 7 mm wide.
