Stages of Cervical Cancer
An ultrasound is a procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs, resulting in echoes. These echoes will form a picture (called a sonogram) of body tissues.
MRI (Magnetic Resonance Imaging)
An MRI is a procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
Staging Test ConclusionsThe results of these tests are viewed together with the results of the original tumor biopsy to determine the stage of cervical cancer.
- Stage 0
- Stage I
- Stage II
- Stage III
- Stage IV
Stage 0 (Carcinoma in Situ)
In stage 0, cancer is only found in the first layer of cells lining the cervix, which means that it has not invaded the deeper tissues of the cervix. Stage 0 is also called carcinoma in situ.
In stage I, cancer is only found in the cervix. This stage of cervical cancer is divided into stages IA and IB, based on the amount of cancer that is found.
In stage IA:
- 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
- The cancer is not wider than 7 millimeters.
In stage IB, one of the following conditions is present:
- Cancer is still within the cervix
- Cancer can be seen with a microscope and is deeper than 5 millimeters or wider than 7 millimeters
- Cancer can be seen without a microscope and may be larger than 4 centimeters.
In stage II, cancer has spread beyond the cervix but not to the pelvic wall (the tissues that line the part of the body between the hips). This cervical cancer stage is divided into stages IIA and IIB, based on how far the cancer has spread.
