In brief: TNM
Cancers are generally staged according to a t-n-m classification.
A tumor is scored based on characteristics of the tumor, nodal spread, and metastasis. So, based on the size or depth of a skin cancer, it will receive a certain t score. The n score is based on whether it has spread to lymph nodes, and the m score tells you if it has spread to a distant site. The combination gives the staging.

In brief: Size, nodes, spread
Most cancers are staged using the tnm system (tumor, nodes, metastasis).
The size/characteristics of the primary tumor give t1-4. Presence, size and location of lymph nodes give n0-3, and presence or absence of mets gives m0-1. Each type of cancer is different for the details of each tnm category. Different combos of tnm give different stages. The higher the stage, the worse the prognosis.

In brief: Depth and metastasis
In melanoma the stage is dependent on the depth of the primary tumor, the prescence of ulceration and mitoses, and whether the cancer has spread to lymph nodes or distant organs.
