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 healthcare provider uses a microscope to see out how different the cancer cells look from normal cells. This is called the cancer grade.
Grade: What the cancer cells look like
The grade of bladder cancer is found by looking at the cancer cells under a microscope. It's based on how much the cancer cells look like normal cells and how many cells are multiplying. The higher the grade, the more different the cells are and the more cells there are multiplying. High-grade cancers are more likely to grow and spread quickly. Knowing the grade can help your healthcare provider predict how fast the cancer will grow and spread.
Low-grade (well-differentiated) cells look fairly normal compared to normal bladder cells. A few of the cells vary in size. Some of the cells are multiplying.

High-grade (poorly differentiated) cells are very uneven in shape. They vary widely in size. A lot of the cells are multiplying. They may also look heaped up or loose compared to the normal pattern of bladder cells.
