In bladder cancer staging, what does a higher N number signify?

Explanation:
Nodal involvement is the N part of the TNM bladder cancer staging. The N category shows how many regional lymph nodes are affected by cancer. A higher N number means more lymph nodes are involved (greater nodal burden) or larger involved nodes, reflecting more extensive regional spread. This contrasts with N0, which means no regional lymph node metastasis. It’s not about distant organ metastasis (that’s M) and it’s not about having fewer nodes involved. A higher N stage signals a worse prognosis and helps guide treatment decisions such as the need for extensive lymph node dissection or systemic therapy.
