The stages of bladder cancer are graded using the TNM staging system.
Tumor (T): How big is the tumor and where is it located?
Nodes (N): Has the tumor spread to the lymph nodes? If so, in what part of the body and how many?
Metastasis (M): Has the cancer metastasized (spread)? If so, in what part of the body and how much?
From there, the cancer will be graded on a scale of 0 to 4 with 0 being the least advanced and 4 being the most advanced.
The staging system for bladder cancer is particularly involved but your doctor will go over it with you in more detail to ensure you’re able to make informed decisions regarding your treatment.
