Depends: The stage of most cancers is determined by 3 factors. T: characteristics of the tumor itself (size, depth, etc), N: involvement of local lymph nodes, and M: metastases (distant spread). These combine in different ways to determine staging, depending on the tumor type. Certain cancer types have other ways to be staged.
