Bladder Cancer: A Guide to Symptoms, Risks and Diagnosis

What Causes Bladder Cancer?

Bladder cancer develops when something goes wrong in the DNA of bladder cells, causing them to grow out of control. Some factors can increase your risk.

Smoking is the most important risk factor. Chemicals from tobacco enter the bloodstream, pass through the kidneys and collect in the urine, where they can affect the bladder lining. Other risk factors include:

• Workplace exposure to chemicals — People who work in the dye, rubber, leather, textile or paint industries may come into contact with chemicals linked to bladder cancer.
• Age and sex — Bladder cancer is more common in men than women and is most often diagnosed after age 55. The median age at diagnosis is 73.
• Chronic bladder irritation — Repeated urinary tract infections, long-term catheter use or chronic bladder inflammation can raise the risk.
• Personal history of bladder cancer — Bladder cancer has one of the highest recurrence rates of any cancer. People who have had it before need consistent follow-up care.
• Family history — Having a close relative with bladder cancer can increase risk and certain inherited gene changes may play a role.

Knowing your risk factors is not about worry, it is about being proactive.

How Is Bladder Cancer Diagnosed?

Diagnosis starts with a review of your symptoms and medical history. If your physician suspects bladder cancer, they will likely refer you to a urologist who specializes in conditions of the urinary tract. Several tests can evaluate what is happening:

• Cystoscopy — A thin, flexible tube with a camera lets your physician look inside the bladder
• Urine cytology — A urine test that checks for cancer cells
• Imaging — CT scan or MRI to look at the urinary system
• Biopsy — A small tissue sample to confirm cancer and identify the type

Grade matters in addition to the stage of cancer. High-grade bladder cancer tends to grow and spread more quickly, while low-grade cancer is generally slower-moving. This helps guide treatment decisions.

Types and Stages of Bladder Cancer

Staging tells us how far the cancer has grown and whether it has spread outside of the bladder. The stage at diagnosis is one of the most important factors in both treatment planning and prognosis.

• Non-muscle invasive bladder cancer (NMIBC) — Cancer stays in the inner lining of the bladder and has not grown into the bladder muscle. We can generally treat NMIBC without removing the bladder.
• Muscle invasive bladder cancer (MIBC) — Cancer has grown into or through the bladder muscle wall. Treatment often involves surgery to remove the bladder, sometimes combined with chemotherapy or radiation.
• Metastatic bladder cancer — Cancer has spread to lymph nodes, nearby organs or other parts of the body. Treatment focuses on controlling the disease and managing symptoms. Newer therapies, including immunotherapy, have improved outcomes for many patients.

Bladder Cancer Treatment Options

Treatment depends on the type, stage and grade of the cancer, as well as your overall health. Most people with bladder cancer will work with a team that includes a urologist, a medical oncologist, and a radiation oncologist to develop a plan that makes sense for their specific situation.

Surgery

If you are diagnosed with early bladder cancer, your surgeon can usually remove the tumor through the urethra. This means no incision is needed. For cancer that has grown deeper into the bladder wall, we may recommend removing the bladder entirely.

Intravesical Therapy

After surgery for early-stage cancer, medication is often delivered directly into the bladder through a catheter. This helps lower the chance of the cancer coming back. The most common option is a treatment that activates the immune system inside the bladder to go after any remaining cancer cells.

Chemotherapy and Radiation

Chemotherapy can be used at different points. We use it before surgery to shrink a tumor, after surgery to reduce the risk of recurrence or on its own when surgery is not the right fit. Radiation therapy targets cancer cells in a specific area. In some cases, we combine radiation with chemotherapy to treat the cancer while preserving the bladder.

Immunotherapy

Immunotherapy helps your immune system recognize and attack cancer cells more effectively. It is now a standard part of treatment for advanced bladder cancer.

Bladder Cancer Survival Rate and Prognosis

Bladder cancer prognosis depends on how early it is found and how it responds to treatment.

When cancer is only in the inner lining of the bladder, the five-year survival rate is approximately 96%. For cancer that has spread to nearby tissue or lymph nodes, survival rates are lower, which is why early detection matters so much.

These numbers are averages. Your situation may differ based on your diagnosis and treatment plan. “The numbers give people a starting point, but they are not your story,” said Dr. Atalla. “I have seen patients do far better than statistics would suggest, and our job is to give every person the best possible chance with the tools we have today.”

Life After a Bladder Cancer Diagnosis

A bladder cancer diagnosis can feel overwhelming, but many people respond well to treatment and continue to live full lives. Bladder cancer can come back, so follow-up care is important. Your care team will stay connected with you and monitor your health over time.

If you notice blood in your urine, changes in urination or anything that does not feel right, do not wait to have it evaluated. A Catholic Health urologist can evaluate your symptoms, coordinate testing and connect you with the right specialists.
