Bladder Cancer– Types & Stages

Understanding Bladder Cancer Types and Stages

The bladder is made up of cells that can sometimes grow unnaturally into cancer cells. There are several types of bladder cancer, including invasive and noninvasive types. No matter what type of cancer you have, there are Phoenix bladder cancer treatment options available to help you.

Common Bladder Cancer Types

Urothelial carcinoma is the most common type of bladder cancer, and is commonly referred to as transitional cell carcinoma (TCC). This type of cancer begins in the urothelial cells that line the inner wall of the bladder and other parts of the urinary tract. Bladder cancer can be further sub-divided into the following categories:

  • Invasive
  • Noninvasive
  • Papillary
  • Flat

Invasive cancer cells are those that have spread into the deepest bladder wall layers and are difficult to treat. They are also more likely to spread into other parts of the body as well. Noninvasive cancer cells have not yet grown into the bladder’s deeper layers and are still found on the transitional epithelium. Noninvasive cancer is easier to treat than invasive cancer and typically has a better outcome

Papillary carcinomas are formed in fingerlike projections that jut from the bladder’s inner surface toward its hollow center. They do not typically grow into the deepest bladder layers and are considered noninvasive. Slow growing, noninvasive papillary cancer usually has a good treatment outcome.

Flat carcinomas do not grow toward the hollow center of the bladder. If they have not spread to the inner bladder cells, they are referred to as noninvasive flat carcinomas and are typically easy to treat.

A Papillary or flat tumor is referred to as an invasive urothelial carcinoma if it grows deeper into the layers of the bladder
