Bladder cancer is a type of cancer that affects the tissues of the bladder, the hollow organ in the lower abdomen that stores urine. According to the American Cancer Society, bladder cancer is the sixth most common cancer in the United States, with an estimated 83,730 new cases and 17,200 deaths in 2021. Like many other types of cancer, bladder cancer can be classified into different stages based on the extent of cancer's spread.
Understanding the stages of bladder cancer is important for patients and their families, as it can help to guide treatment decisions and provide a sense of what to expect in terms of prognosis and survival rates.
In this article, we will provide an overview of the different stages of bladder cancer, from the earliest, non-invasive stage to the most advanced, metastatic stage. We will describe the characteristics of each stage, the available treatment options, and the expected outcomes for patients with each stage.
Stages of Bladder Cancer and Treatment
Stage 0 - Non-invasive bladder cancer
Stage 0 bladder cancer, also known as non-invasive bladder cancer, is the earliest stage of bladder cancer. In this stage, cancer cells are found only in the inner lining of the bladder and have not yet invaded the deeper layers of the bladder wall or spread to other parts of the body.
There are two types of non-invasive bladder cancer: papillary carcinoma and carcinoma in situ. Papillary carcinoma is a type of cancer that grows outward from the lining of the bladder in finger-like projections called papillae. Carcinoma in situ, on the other hand, is a type of cancer that remains in the inner lining of the bladder and does not form any papillae.
Treatment options for stage 0 bladder cancer may include transurethral resection of the bladder tumor (TURBT), a procedure in which a cystoscope is inserted into the bladder to remove the cancerous tissue, or intravesical therapy, in which a liquid drug is put into the bladder through a catheter to kill any remaining cancer cells.
The prognosis for stage 0 bladder cancer is generally very good, with a five-year survival rate of over 95%. However, there is a risk that cancer may recur or progress to a more advanced stage, so close monitoring and follow-up care are important for patients with this stage of bladder cancer.
Stage I - Early-stage bladder cancer
Stage I bladder cancer is the second stage of bladder cancer and is still considered an early stage. At this stage, cancer has grown through the inner lining of the bladder and into the connective tissue beneath, but it has not yet spread to the muscle layer of the bladder or other nearby organs.
Symptoms of stage I bladder cancer may include blood in the urine, frequent urination, pain or discomfort during urination, and lower back pain.
Treatment options for stage I bladder cancer may include TURBT, which is often used to remove the cancerous tissue and to examine the depth of cancer invasion. Depending on the results of the TURBT, other treatment options may include intravesical therapy, which uses medication to kill any remaining cancer cells in the bladder, or immunotherapy, which uses the body's immune system to attack cancer cells.
The five-year survival rate for stage I bladder cancer is generally high, ranging from 88% to 98%, depending on the specific characteristics of cancer and the treatment received. However, like stage 0 bladder cancer, there is a risk that cancer may recur or progress to a more advanced stage, so close monitoring and follow-up care are important for patients with this stage of bladder cancer.
Stage II - Invasive bladder cancer
Stage II bladder cancer is an invasive form of bladder cancer in which cancer has spread to the muscle layer of the bladder, but has not yet spread to nearby lymph nodes or other organs. This stage of bladder cancer is more advanced than stage I and may require more aggressive treatment.
Symptoms of stage II bladder cancer may include blood in the urine, frequent urination, pain or discomfort during urination, lower back pain, and a feeling of incomplete bladder emptying.
Treatment options for stage II bladder cancer may include surgery to remove part or all of the bladder, radiation therapy to kill cancer cells, chemotherapy to destroy cancer cells or a combination of these treatments. The type of treatment recommended will depend on the individual patient's specific case, including the size and location of the tumor, the extent of cancer's spread, and the patient's overall health and preferences.
The five-year survival rate for stage II bladder cancer ranges from approximately 50% to 70%, depending on the specific characteristics of cancer and the treatment received. However, it's important to note that survival rates can vary widely depending on individual factors, and some patients may experience longer-term survival or even complete remission of their cancer with the appropriate treatment and follow-up care.
Stage III - Locally advanced bladder cancer
Stage III bladder cancer is a locally advanced form of bladder cancer in which cancer has spread beyond the bladder and into nearby tissues or organs, such as the prostate, uterus, or vagina. This stage of bladder cancer is more advanced than stage II and may require more aggressive treatment.
Symptoms of stage III bladder cancer may include blood in the urine, pain in the lower back or pelvis, weight loss, and swelling in the legs.
Treatment options for stage III bladder cancer may include surgery to remove the bladder and nearby lymph nodes, radiation therapy to kill cancer cells, chemotherapy to destroy cancer cells, or a combination of these treatments. The type of treatment recommended will depend on the individual patient's specific case, including the size and location of the tumor, the extent of cancer's spread, and the patient's overall health and preferences.
The five-year survival rate for stage III bladder cancer ranges from approximately 30% to 50%, depending on the specific characteristics of cancer and the treatment received. However, it's important to note that survival rates can vary widely depending on individual factors, and some patients may experience longer-term survival or even complete remission of their cancer with the appropriate treatment and follow-up care.
Stage IV - Metastatic bladder cancer
Stage IV bladder cancer is the most advanced stage of bladder cancer, in which cancer has spread to other parts of the body beyond the bladder, such as the lungs, liver, or bones. This stage of bladder cancer is also known as metastatic bladder cancer, and it can be difficult to treat.
Symptoms of stage IV bladder cancer may include blood in the urine, pain in the lower back or pelvic area, weight loss, fatigue, and swelling in the legs.
Treatment options for stage IV bladder cancer may include chemotherapy, radiation therapy, immunotherapy, targeted therapy, or a combination of these treatments. The goal of treatment at this stage is often to control the growth and spread of cancer, manage symptoms, and improve quality of life.
The five-year survival rate for stage IV bladder cancer ranges from approximately 5% to 15%, depending on the specific characteristics of cancer and the treatment received. However, it's important to note that survival rates can vary widely depending on individual factors, and some patients may experience longer-term survival or even complete remission of their cancer with the appropriate treatment and follow-up care. In some cases, clinical trials may also be available for patients with stage IV bladder cancer, offering new and innovative treatment options.

Conclusion
In conclusion, bladder cancer is a complex disease that can be classified into different stages based on the extent of cancer's growth and spread. Stage 0 and stage I bladder cancers are early stages of the disease, while stage II, stage III, and stage IV represent increasingly advanced stages.
Treatment options and survival rates vary widely depending on the stage of cancer, as well as the individual patient's specific case, including the size and location of the tumor, the extent of the cancer's spread, and the patient's overall health and preferences.
However, with appropriate treatment and follow-up care, many patients with bladder cancer can experience improved quality of life and even longer-term survival. It is important to consult with a medical professional and develop a personalized treatment plan that is tailored to your individual needs and circumstances if you or someone you know is diagnosed with bladder cancer.
