As far as I know, most cancers are staged between I to IV with some being just up to stage III. These staging systems are based on the tumor size (T), regional status of lymph nodes (N), and presence of distal metastases (M). Thus, this is called the TNM type of staging. I'm not sure where you have heard of a stage V and I suggest you verify the information. Stage IV cancers are usually the metastatic or incurable ones and the stage I cancers are the early stage cancers. Regards.
