Nevermind - found the info :
The stage of a cancer describes its size and whether it has spread beyond its original site. Knowing the extent of the cancer and the grade helps the doctors to decide on the most appropriate treatment.
The stages of cervical cancer are described below:
Stage 1 The cancer cells are only within the cervix.
Stage 2 The tumour has spread into surrounding structures such as the upper part of the vagina or tissues next to the cervix.
Stage 3 The tumour has spread to surrounding structures such as the lower part of the vagina, nearby lymph nodes, or tissues at the sides of the pelvic area. Sometimes a tumour that has spread to the pelvis may press on one of the ureters (the tubes through which urine passes from the kidneys to the bladder). If the tumour is causing pressure on the ureter there may be a build up of urine in the kidney.
Stage 2 or 3 tumours may be called locally advanced cervical cancer.
Stage 4 The tumour has spread to the bladder or bowel or beyond the pelvic area. This stage includes tumours that have spread into the lungs, liver or bone, although these are not common.
If the cancer comes back after initial treatment this is known as recurrent cancer.

Grading
Grading refers to the appearance of the cancer cells under the microscope. The grade gives an idea of how quickly the cancer may develop. There are three grades: grade 1 (low grade), grade 2 (moderate grade) and grade 3 (high grade). Low grade means that the cancer cells look very like the normal cells of the cervix. They are usually slowly growing and less likely to spread. In high-grade tumours the cells look very abnormal. They are likely to grow more quickly and are more likely to spread.
