Stages, types and grades of vulval cancer
The tests and scans you have to diagnose vulval cancer give information about:
- the type of cell the cancer started in and where it began
- the size of the cancer and whether it has spread. This is the stage.
- how abnormal the cells look under the microscope. This is the grade.
In the UK, doctors usually stage vulval cancer according to the FIGO system. FIGO stands for International Federation of Gynaecology and Obstetrics. There are 4 main stages in this system, from 1 to 4.
You might also be told about the TNM stage, or you may see this on your pathology report.
