Overview
Classification
In the United States, bladder cancers usually start from the cells lining the bladder (called transitional cells).
These tumors are classified based on the way they grow:
- Papillary tumors have a wart-like appearance and are attached to a stalk.
- Nonpapillary (sessile) tumors are much less common. However, they are more invasive and have a worse outcome.

Grading
According to the WHO grading criteria, there are three grades of transitional cell carcinoma based on the degree of cellular differentiation:[1]
| Grade | Description |
|---|---|
|
Grade 1 |
|
|
Grade 2 |
|
|
Grade 3 |
