Bladder cancer is usually treatable - especially when caught early. Unfortunately the disease also has one of the highest rates of recurrence, and it’s relatively common for people who are diagnosed with bladder cancer to experience a return of their cancer at least once following initial treatment. For some types of bladder cancer, the risk of recurrence is very high.
There are a number of different reasons why bladder cancer can recur and it is not always easy to predict who is at risk. As a result, regular monitoring and surveillance following treatment is important for helping to detect bladder cancer recurrence early, and ensuring the best chance of a good outcome for patients.

Why Can Bladder Cancer Recur?
Bladder cancer develops when cells in the bladder begin to grow, divide, and spread in an uncontrolled way, leading to the formation of a malignant tumor. Although treatments can be very effective at removing tumors, a small number of cancerous cells can sometimes remain. Bladder cancer can recur when cancer cells left behind begin to grow again, after treatment has finished.
Sometimes patients who have been previously treated for bladder cancer can go on to develop a different type of cancer in the bladder, or elsewhere in the body- this is known as a secondary cancer.
Who Is Most at Risk of Bladder Cancer Recurrence?
A person’s individual risk for bladder cancer recurrence can depend on a number of different factors, including the type and stage of cancer, success of initial treatment, and demographic and lifestyle factors such as age and smoking history.1
Researchers don’t yet understand all of the reasons why bladder cancer can recur, or who will definitely experience recurrence of their cancer.
This is one of the reasons why physicians strongly recommend that people who have previously been diagnosed with bladder cancer have regular ongoing check-ups following treatment. This is sometimes called ‘active surveillance’.
How Often Does Bladder Cancer Recur?
Recurrence rates for bladder cancer can be quite high compared to other types of cancer. Generally, over half of all people who develop bladder cancer may experience recurrence of their cancer following treatment.
Non-muscle invasive bladder cancer recurrence
‘Non-muscle invasive’ bladder cancer is the most common bladder cancer diagnosed. It is considered to be early-stage, as the cancer cells are present only in the inner lining of the bladder.
Chances of recurrence can be very high for non-muscle invasive bladder cancer. Around 31% to 78% of people with this cancer will develop recurrence or a secondary bladder cancer within 5 years following treatment, depending on risk-factors.2
Muscle-invasive bladder cancer recurrence
‘Muscle invasive’ bladder cancer means the cancer has grown into the muscle layer of the bladder. This cancer is less commonly diagnosed, but can be more aggressive and have a high rate of recurrence and progression. Patients with muscle-invasive bladder cancer often need a more aggressive treatment regime, and chances of recurrence following treatment can still be around 30% to 54%.3
It can also be very difficult to predict when bladder cancer may recur. Bladder cancer can sometimes come back up to 5, 10, or even 15 years after treatment.4,5
This means that if you have been previously diagnosed with bladder cancer, you may be asked to undergo extra surveillance check-ups and monitoring for any recurrence for many years after initial treatment.
Why Is Early Detection of Bladder Cancer Recurrence Important?
Early detection can help to ensure any recurrence is treated promptly. The sooner new cancer growth is detected, the more time and options are available for managing the condition appropriately.
Many bladder cancers that recur remain treatable and do not spread or progress. But there is always the chance that as the cancer comes back, it will progress to a more dangerous form. For example, for patients with non-muscle invasive bladder cancer, 10% to 30% may eventually experience disease progression to life-threatening muscle-invasive bladder cancer, though this figure is much smaller for low-risk tumors.6
Research suggests that early bladder cancer detection through routine clinical check-ups and using diagnostic tests for those with symptoms or at risk could be an effective way to help improve patient survival.7
As well as helping to detect any potentially problematic changes in good time, some people also find that keeping in regular touch with a healthcare team and following a regular schedule of follow-up health checks can be reassuring, and help to provide a sense of control while adapting to life after cancer.
Recommendations for Bladder Cancer Surveillance and Monitoring
If you’ve been diagnosed with bladder cancer, your healthcare team will often develop a personalized follow-up surveillance plan with you outlining the recommended number and type of check-ups you will need after treatment. This plan is usually tailored based on medical guidelines and reflects the risk of recurrence of bladder cancer.
Guidelines for surveillance of bladder cancer recurrence
The frequency and type of surveillance check-ups recommended for bladder cancer recurrence is often based on the presence or absence of a number of individual risk factors, and whether your cancer is categorized as low-risk, intermediate-risk, or high-risk.
In general terms, American Urological Association guidelines recommend a medical check-up within 3 to 4 months following treatment, then again up to 4 times a year for the first 4 or 5 years, and annually, or at the patient’s and physician’s discretion after that.8
If several years of surveillance have gone by and no cancer recurrence is detected, a single check-up once a year may then be enough, depending on various factors.
Patient monitoring for signs and symptoms of bladder cancer
Staying aware for possible signs and symptoms of bladder cancer is also an important way patients can help to detect any early possible signs of bladder cancer recurrence. Appearance of blood in urine can be the most common symptom of a possible cancer recurrence.
Other symptoms such as changes to urination frequency or urgency, and pain during urination can also be important indicators. You should always discuss any new symptoms or worrying changes with a physician.
Procedures Used During Bladder Cancer Monitoring and Surveillance
A patient’s follow-up surveillance plan might contain a number of different medical exams and procedures.
Cystoscopy bladder examinations are recommended as an integral part of a patient’s follow-up plan. During cystoscopy, a thin tube called a cystoscope is inserted into the bladder through the urethra. A light and camera are then used to check the lining of the bladder. If any unusual areas are noticed, a small sample of tissue called a ‘biopsy’ can be taken for analysis in a laboratory.
Non-invasive genomic urine tests
In many cases, non-invasive urine-based biomarker tests such as Cxbladder Monitor can also be used as part of a patient’s follow-up surveillance plan to help rule out bladder cancer recurrence. Using Cxbladder Monitor in combination with cystoscopy on an alternating schedule can help to reduce the frequency of cystoscopy required.

Other procedures and tests used during check-ups
A number of other procedures may also be used alongside cystoscopy and non-invasive urine testing of biomarkers as part of a patient’s follow-up surveillance plan. Depending on patient need, additional procedures can include radiographic imaging to visualize the upper urinary tract, and also urine cytology, which involves microscopic examination of urine for cancer cells.
If you’re a patient monitoring for bladder cancer recurrence, ask your doctor about Cxbladder
Cxbladder is a cutting-edge genomic urine test that quickly and accurately detects or rules out bladder cancer. The test combines clinical risk factor markers with genetic information, measuring five biomarker genes to detect the presence or absence of bladder cancer in hematuria patients and those being monitored for recurrence.
Because bladder cancer has a high risk of recurrence, patients that have been treated have unique monitoring needs to protect against the threat of the disease returning. Cxbladder Monitor is an accurate and non-invasive surveillance alternative designed to rule out the return of bladder cancer with a single urine sample. In many cases this reduces the need for frequent cystoscopies which can be both uncomfortable and inconvenient.
