Microscopic clues may forecast bladder Cancer's next move

This study examines two microscopic details in bladder cancer tumors—how deep early cancer cells have invaded and whether small clusters of cells are present at the tumor's edge. Researchers will look at tissue samples from 100 patients to see if these features can predict if the cancer will come back or spread. The goal is to better understand which patients need more aggressive treatment, but no new therapy is being tested.
