Diagnosis
Recurrent bladder cancer often is found during follow-up tests after treatment. Sometimes symptoms lead to tests that find the cancer. Your healthcare professional may recommend more tests to confirm that the cancer has come back.
If your bladder wasn't removed during treatment, your healthcare professional might do a cystoscopy exam to look inside the bladder for signs of cancer. If your bladder was removed, imaging tests might be used to look for cancer in the urinary tract or other parts of the body. Your healthcare team also may remove a tissue sample for testing.
Cystoscopy
Cystoscopy is a procedure that lets a healthcare professional see inside the bladder. During cystoscopy, a healthcare professional puts a small, narrow tube, called a cystoscope, through the urethra. The urethra is the tube that takes urine from the bladder out of the body. The cystoscope has a lens the healthcare professional uses to see inside the urethra and bladder to check for signs of disease.
Imaging tests
Imaging tests make pictures that the healthcare team uses to look for signs of cancer. The tests may make pictures of the urinary tract or other parts of the body.
Tests that look for cancer in the urinary tract include:
- CT urogram. During a CT urogram, a contrast material is put into a vein in the hand. The contrast flows into the kidneys, ureters and bladder. X-ray images taken during the test show a detailed view of the urinary tract. Those images help the healthcare team see any areas that might be cancer.
- Retrograde pyelogram. A retrograde pyelogram is an X-ray exam used to get a detailed look at the upper urinary tract. During this test, a thin tube, called a catheter, is put through the urethra and into the bladder. Contrast material then is put into the catheter and flows into the ureters and kidneys while X-ray images are taken of these areas.
Tests that look for cancer in other parts of the body include:
- Bone scan. A bone scan uses nuclear imaging to make pictures. Nuclear imaging involves using small amounts of radioactive substances, called radioactive tracers. A special camera that can detect the tracers also is used along with a computer.
- Computerized tomography (CT) scan. A CT scan is a type of imaging that uses X-ray techniques to create detailed images of the body. Then a computer creates cross-sectional images, also called slices, of the bones and soft tissues inside the body.
- Magnetic resonance imaging (MRI). MRI uses a magnetic field and radio waves to create pictures of the inside of the body.
- Positron emission tomography (PET) scan. A PET scan is a nuclear imaging test. It uses a radioactive tracer that's put into a vein. The tracer contains a substance that helps it stick to the cells that the test is looking for. The PET images show the places where the tracer builds up.
Not everyone needs every test. Your healthcare team chooses the imaging tests based on your symptoms and your situation.
Biopsy
A biopsy is a procedure to remove a sample of tissue for testing in a lab. If your bladder wasn't removed during previous cancer treatment, a healthcare professional may get a tissue sample during a cystoscopy exam. The healthcare professional may pass a tool through the scope and into the bladder to do a biopsy.
If your bladder was removed to treat a previous cancer or if the cancer spreads to other parts of the body, the healthcare professional may get the tissue sample in a different way. How the healthcare professional does this depends on where the cancer is in your body.
Tests in the lab can confirm that the cancer is a bladder cancer recurrence. Tests also can look at the DNA changes that are present in the cancer cells. The results may help your healthcare team understand your prognosis and make a treatment plan.
Transurethral resection of bladder tumor
Transurethral resection of bladder tumor (TURBT) is a procedure to diagnose bladder cancer and to remove small cancers from the inside of the bladder. During the procedure, a healthcare professional passes an electric wire loop through a cystoscope and into the bladder. The electric current in the wire is used to cut away or burn away the cancer. Sometimes a high-energy laser may be used instead of the electric wire loop.
If your bladder wasn't removed, TURBT might be part of your diagnosis. If the cancer affects only the inside lining of the bladder, TURBT also might help treat the cancer.

Treatment
Treatments for recurrent bladder cancer include procedures to remove the cancer, including surgery to remove the bladder, medicines and radiation therapy. Medicines to treat recurrent bladder cancer include chemotherapy, immunotherapy and others.
The treatments that your healthcare team recommends may depend on where the cancer comes back. When cancer comes back in the bladder, treatment usually involves removing the cancer. The type of procedure the healthcare team recommends may depend on whether the cancer has grown into the bladder wall or whether it has a high risk of growing into it.
When cancer comes back in places other than the bladder, treatment often starts with medicines. How well the medicines work might help your care team decide what other treatments to consider.
When making your treatment plan, your care team also thinks about your preferences and your goals for treatment.
Treatment for cancer recurrence in the bladder
If bladder cancer comes back in the bladder, treatment usually starts with a procedure to remove the cancer.
TURBT with intravesical medicines. Transurethral resection of bladder tumor (TURBT) is a procedure to remove cancer that affects the inner layers of the bladder only. During the procedure, a healthcare professional passes tools through a cystoscope and into the bladder. The tools are used to remove the cancer.
After TURBT, your healthcare team may recommend having medicines put into the bladder. Giving medicines this way is called intravesical therapy. Which medicines you get may depend on your situation and whether you had this treatment in the past.
TURBT with intravesical medicines may be used to treat recurrent bladder cancer that affects only the inner lining of the bladder. This is called non-muscle-invasive bladder cancer.
Bladder removal surgery. Cystectomy is surgery to remove all or part of the bladder. During a partial cystectomy, a surgeon takes out only the area of the bladder that has the cancer.
During a radical cystectomy, a surgeon takes out all of the bladder and the lymph nodes around it. Radical cystectomy typically also includes removal of the prostate gland and seminal vesicles or the uterus, ovaries and part of the vagina. The surgeon then creates a way for urine to leave your body, called a urinary diversion.
Medicines, such as chemotherapy and immunotherapy, may be used before or after surgery. Radiation therapy also may be used.
Bladder removal surgery might be used when the recurrent bladder cancer grows into the wall of the bladder. This is called muscle-invasive bladder cancer. Cystectomy also may be used if the cancer comes back after previous bladder preservation therapy.
Cystectomy is sometimes used to treat non-muscle-invasive bladder cancer. It might be used if the cancer has a high risk of becoming invasive or if it comes back soon after treatment.
Bladder preservation. Sometimes, people with bladder cancer that has gone into the bladder's muscle layer don't want to have the bladder removed. In that situation, the healthcare team may use a combination of treatments instead. Called trimodality therapy, this approach uses TURBT, chemotherapy and radiation therapy.
First, a surgeon uses TURBT to take out as much of the cancer as possible while keeping bladder function. Then, after the surgery, chemotherapy is given along with radiation therapy. If any cancer remains after trimodality therapy, a radical cystectomy may be needed.
Bladder preservation may be an option for those who prefer not to have bladder removal surgery or for whom surgery isn't recommended.
Treatment for cancer that comes back outside of the bladder
When bladder cancer comes back in places other than the bladder, treatment may start with medicines.
- Chemotherapy. Chemotherapy treats cancer with strong medicines.
- Immunotherapy. Immunotherapy for cancer is a treatment with medicine that helps the body's immune system kill cancer cells. The immune system fights off diseases by attacking germs and other cells that shouldn't be in the body. Cancer cells survive by hiding from the immune system. Immunotherapy helps the immune system cells find and kill the cancer cells.
- Antibody-drug conjugates. Antibody-drug conjugates are medicines that combine targeted therapy with chemotherapy. These medicines use targeted therapy to identify the cancer cells and deliver chemotherapy directly to those cells.
- Targeted therapy. Targeted therapy for cancer is a treatment that uses medicines that attack specific chemicals in the cancer cells. By blocking these chemicals, targeted treatments can cause cancer cells to die.
Which medicines you get may depend on your cancer, your overall health and which treatments you've had in the past. If the medicines work well to control the cancer, other treatments, such as surgery or radiation therapy, may be used to treat the remaining cancer.

Coping and support
Finding out your bladder cancer has returned can be more upsetting than your first diagnosis. As you sort through your emotions and make decisions about treatment, here are some ideas that may help you cope.
Learn more about recurrent bladder cancer
Ask your healthcare professional about your cancer, including your treatment options and, if you like, your outlook. As you learn more about recurrent bladder cancer, you may become more confident in making treatment decisions.
Keep friends and family close
Keeping your close relationships strong may help you deal with your recurrent bladder cancer. Friends, family and other people you trust can provide the practical support you may need, such as helping take care of household tasks if you're in the hospital. And they may serve as emotional support when you feel overwhelmed by cancer.
Find someone to talk with
Find a good listener who you can talk with about your hopes and fears. This may be a friend or family member. You also may find it helpful to talk with a counselor, medical social worker or clergy member. Or join a cancer support group for understanding and guidance.
Ask your healthcare team about local support groups, or contact the American Cancer Society or another cancer organization in your area to find resources. Find support online through Mayo Clinic Connect, a community where you can connect with others for support, practical information and answers to everyday questions.
Preparing for your appointment
Make an appointment with a healthcare professional if you have any symptoms that worry you. If your healthcare team suspects you might have recurrent bladder cancer, you might be referred to a doctor who specializes in treating diseases and conditions of the urinary tract, called a urologist. Or you may be referred to a doctor who treats cancer, called an oncologist. Here are some things you can do to get ready for your appointment.
What you can do
When you make the appointment, ask if there's anything you need to do before your appointment, such as not eating or drinking for a certain amount of time. Make a list of:
- Your symptoms, including any that don't seem related to the reason for your appointment.
- Key personal information, including major stresses, recent life changes and family medical history.
- All medicines, vitamins and other supplements you take, including the doses.
- Questions to ask your healthcare professional.
Take a family member, friend or another trusted person with you, if possible, to help you remember the information you're given.
For recurrent bladder cancer, basic questions to ask your healthcare professional include:
- Do I have recurrent bladder cancer, or could my symptoms be caused by another condition?
- What tests do I need?
- What are my treatment options?
- Can any treatments cure my bladder cancer?
- What are the possible risks of each treatment?
- Should I see a specialist?
- Do I need follow-up appointments?
- Are there brochures or other printed materials that I can take with me? What websites do you recommend?
Be sure to ask any other questions you may have.
What to expect from your care team
Your healthcare professional may ask:
- When did your symptoms start?
- Are your symptoms always present, or do they come and go?
- How bad are your symptoms?
- What, if anything, makes your symptoms better?
- What, if anything, makes your symptoms worse?
