In bladder cancer TNM staging, what does increasing T stage indicate?

Explanation:
In bladder cancer TNM staging, the T descriptor measures how far the primary tumor has invaded the bladder wall and surrounding structures. When the T stage increases, the tumor has invaded more deeply and/or spread to adjacent tissues, reflecting a greater extent of tumor growth. That’s why the statement about greater extent of tumor growth is the correct interpretation. Less invasion would correspond to a lower T stage, so that option doesn’t fit. Differentiation refers to histologic grade, not T stage. Metastasis probability is about spread to lymph nodes or distant sites (N and M), not the extent of the primary tumor’s local invasion.
