There are four stages of cervical cancer. Each
stage is broken into sections. Staging information
helps doctors compare an individual situation
to other patients with cervical cancer. They
can compare clinical studies on groups of patients
in similar stages of the cancer to determine
how the cancer may behave, and how different
treatments may work.
Stage
0: Carcinoma in situ – the
tumor has only grown on the cells lining
the cervix. |
 |
Stage
I: The cancer has spread into the
cervix but has not gone any further.
This stage is divided into the following
groups: |
- Stage IA1 – The doctor cannot see this cancer without a microscope. It is less than 3 mm deep and less than 7 mm wide.
- Stage IA2 – The doctor cannot see this cancer without a microscope. It is between 3 and 5 mm deep but still less than 7 mm wide.
- Stage IB1 – A doctor can see this cancer with the naked eye. It is no bigger than 4 cm in size.
- Stage IB2 – A doctor can see this cancer with the naked eye. It is larger than 4 cm in size.

Stage
II: The cancer has spread to body
parts outside the cervix, but not outside
of the pelvis. Stage II is divided into
the following groups: |
- Stage IIA – This cancer extends to your upper vagina. It has not spread any further than the vagina.
- Stage IIB – This cancer has spread to the tissues surrounding your vagina and cervix but not yet to the wall of the pelvis.
|
|
Stage
III: The cancer has spread to the
top of your vagina or outside the pelvic
wall. It is broken into these groupings: |
- Stage IIIA – The cancer has spread to the lower third of your vagina. It has not spread to the wall of your pelvis.
- Stage IIIB – The cancer has spread to the soft tissues surrounding your vagina and cervix all the way to the wall of the pelvis. It may block one or both of the tubes that drains the kidneys.

|
Stage
IV: With this stage, the cancer
has spread to other parts of your body
such as the bladder, rectum, or lungs.
Stage IV is further divided in these
ways. |
- Stage IVA – The cancer has spread
to nearby organs.
- Stage IVB – The
cancer has spread to distant organs,
such as the lungs.
