People who have received these treatments should follow the monitoring and follow-up advice provided by their medical team.
5. Chronic bladder irritation and other medical factors
Certain long-term bladder conditions may be associated with increased risk.
These include chronic irritation, some persistent infections, bladder stones, and long-term urinary catheter use.
In particular, infection with the parasite Schistosoma haematobium is associated with a type of bladder cancer in regions where the parasite is common.
This infection is more prevalent in certain parts of Africa and the Middle East and is not a common explanation for bladder cancer in most other regions.
6. Family history
Having a close relative with bladder cancer may be associated with increased risk.
Inherited genetic factors may contribute in some families, although most bladder cancer cases are not explained by a single inherited cause.
It is important to remember that having one or more risk factors does not mean someone will definitely develop bladder cancer.
Likewise, people without obvious risk factors can still develop the disease.
CHAPTER 10: HOW DO DOCTORS DIAGNOSE BLADDER CANCER?
Recognizing symptoms is only the first step.
A diagnosis requires medical evaluation and appropriate tests.
The doctor will usually begin by asking about the patient's symptoms, medical history, medication use, smoking history, and possible workplace exposures.
They may ask:
-
When did the urinary symptoms begin?
-
Has there been visible blood in the urine?
-
Has the bleeding occurred more than once?
-
Is there pain or burning during urination?
-
How often does the person need to use the bathroom?
-
Has there been unexplained weight loss or fatigue?
-
Is there a personal or family history of urinary tract problems?
These questions help the doctor determine which investigations may be necessary.
Urine tests
A urine sample can be examined to identify blood, signs of infection, and other abnormalities.
A urinalysis may detect small amounts of blood that cannot be seen with the naked eye.
If infection is suspected, a urine culture may help identify bacteria and guide treatment.
In selected cases, doctors may recommend urine cytology, which examines cells in the urine for abnormal features.
However, urine tests alone cannot reliably confirm or exclude every case of bladder cancer.
Imaging tests
Imaging may be used to examine the urinary tract and identify abnormalities.
Depending on the patient's condition, doctors may recommend ultrasound, CT scans, or other imaging studies.
These tests can provide information about the kidneys, ureters, bladder, and surrounding structures.
The choice depends on the patient's symptoms, medical history, kidney function, and clinical findings.
Cystoscopy
One of the most important procedures used to investigate suspected bladder cancer is cystoscopy.
During cystoscopy, a doctor inserts a thin instrument with a small camera through the urethra to examine the inside of the bladder.
This allows the doctor to look for abnormal areas, suspicious growths, or other changes.
If a suspicious tumor is found, the patient may need a procedure called transurethral resection of bladder tumor, often abbreviated as TURBT.
During this procedure, the doctor removes the visible tumor through the urethra so that tissue can be examined in a laboratory.
Biopsy and pathology
A tissue sample is examined by a pathologist to determine whether cancer cells are present.
If cancer is confirmed, the laboratory assessment helps establish the type and grade of the tumor.
Doctors may also recommend additional tests to determine how deeply the tumor has grown and whether it has spread.
The results help guide treatment decisions.
CHAPTER 11: WHY EARLY DIAGNOSIS CAN MAKE A DIFFERENCE
Bladder cancer is not a single condition with one predictable outcome.
Its behavior depends on factors such as tumor type, grade, stage, and whether it has invaded the muscle layer of the bladder.
Some bladder cancers are classified as non-muscle-invasive. This means the tumor has not grown into the bladder's muscular wall.
Others are muscle-invasive, meaning cancer cells have reached deeper layers.
The distinction is important because treatment approaches can differ considerably.
When bladder cancer is diagnosed at an earlier stage, doctors may have more treatment options, and the disease may be easier to manage.
Some early-stage tumors can be removed through a procedure performed through the urethra. Depending on the risk of recurrence or progression, additional treatment may be placed directly into the bladder.
More advanced disease may require a combination of surgery, chemotherapy, immunotherapy, radiation therapy, or other treatments.
Not every patient needs the same treatment.
Doctors consider the tumor's characteristics, the patient's general health, and personal circumstances before recommending a plan.
Early diagnosis does not guarantee a cure, but it can provide an opportunity to identify the disease before it becomes more difficult to treat.
That is why unexplained blood in the urine and persistent urinary changes should be investigated rather than ignored.
CHAPTER 12: WHAT TREATMENTS MAY BE AVAILABLE?
Treatment depends on the type, grade, and stage of bladder cancer.
For non-muscle-invasive bladder cancer, doctors may remove the tumor through TURBT.
Some patients may then receive intravesical therapy, in which medication is placed directly into the bladder through a catheter.
One commonly used treatment is Bacillus Calmette-Guérin, or BCG, which stimulates an immune response inside the bladder.
Other patients may receive chemotherapy delivered directly into the bladder.
For muscle-invasive bladder cancer, treatment may involve more extensive surgery, chemotherapy, immunotherapy, or combinations of these approaches.
In some cases, doctors recommend removal of the bladder, a procedure known as radical cystectomy.
When the bladder is removed, surgeons must also create a new way for urine to leave the body. Several urinary diversion techniques are available, and the most suitable option depends on the individual patient.
Some patients may be candidates for bladder-preserving treatment involving a combination of chemotherapy and radiation therapy.
For advanced or metastatic bladder cancer, systemic treatments may include chemotherapy, immunotherapy, targeted therapies, or antibody-drug conjugates, depending on the tumor and the patient's circumstances.
