Grading of Bladder Cancer
Once cancer has been diagnosed, the next step is to choose the best way to treat it. To help do this, your doctor checks what the cancer cells look like (the cancer
grade).
Grade: What the Cancer Cells Look Like
The grade of bladder cancer is found by looking at cancer cells under a microscope. The grade is based on what the cancer cells look like and how many cells are multiplying. The higher the grade, the more uneven the cells are and the more cells are multiplying. Knowing the grade can help your doctor predict how fast the cancer will grow and spread.
| 
| Low Grade
Low-grade cells look relatively normal. A few of the cells vary in size. Some of the cells are multiplying.
|
| 
| Middle Grade Middle-grade cells look more uneven in shape and vary more in size. More cells are multiplying. |
| 
| High Grade
High-grade cells are very uneven in shape. They vary widely in size. Almost all of the cells are multiplying.
