When bladder cancer spreads, it first invades the bladder wall, which is made up of four distinct layers. It can take some time for cancer to penetrate all of these layers, but once it has, it can then spread into the surrounding fatty tissues and lymph nodes.

What size bladder tumor is considered large?

First, there is no common agreement regarding what size a bladder tumor constitutes a “large tumor.” In the literature, a large tumor has been variously defined as one with a total resected weight > 50 g, a weight ≥15 g, and a diameter > 5 cm [2-4].

Stage 3. Around 40 out of 100 people (around 40%) survive their cancer for 5 years or more after they are diagnosed. Stage 3 means that the cancer has grown through the muscle into the fat layer. It may have spread outside the bladder to the prostate, womb or vagina.

How long can you live with Stage 4 bladder cancer?

The 5-year survival rate is the rate of surviving for 5 years after a cancer diagnosis. For bladder cancer, if the cancer has spread to the regional lymph nodes, the 5-year survival rate is 36.3 percent . If it has spread to a more distant site, the 5-year survival rate is 4.6 percent .

What is the prognosis for high grade bladder cancer?

The general 5-year survival rate for people with bladder cancer is 77%. However, survival rates depend on many factors, including the type and stage of bladder cancer that is diagnosed. The 5-year survival rate of people with bladder cancer that has not spread beyond the inner layer of the bladder wall is 96%.

Other patients may have another type of procedure called a transurethral resection of bladder tumor ( TURBT ), in which the bladder tumor (s) are removed from the bladder lining. The surgeon may use a procedure called fulguration to try to eliminate cancer cells that remain after the tumor is removed.

How to tell if bladder cancer is stage T3A?

In a stage T3b bladder tumor, the bladder cancer cells have grown into the perivesical tissue and are large enough that they are visible using an imaging test or they can be felt by a healthcare professional.

What is stage 2 bladder cancer?

A diagnosis of stage 2 bladder cancer means that the bladder cancer cells have grown into the muscle layer of the bladder wall. 1,2 This is also called muscle-invasive bladder cancer. Stage 2 bladder cancer includes the following combined TNM stages:

How to determine bladder cancer stage?

When a patient is diagnosed with bladder cancer, healthcare professionals use a combination of information from diagnostic tests, and possibly surgery, to determine the patient’s overall bladder cancer stage. 1,2 This is done using combined information about the bladder tumor (T), whether there are cancer cells in lymph nodes (N) close to the bladder, and whether the cancer cells have metastasized (M), or spread, to any parts of the body distant from the bladder.

What type of tumor is T2B?

If the tumor is type T2b, the bladder cancer cells have grown through the superficial muscle and into the deep muscle of the bladder. However, the cancer cells have not yet spread into the layer of fatty tissue that surrounds the outer part of the bladder muscle.

How to tell the stage of bladder cancer?

The tumor stage tells how much of the tissue has the cancer. Doctors can tell the grade and stage of bladder cancer by taking a small sample of the tumor. This is called a biopsy. A pathologist in a lab examines the sample under a microscope and determines the grade and stage of the cancer.
