However, a change from someone's normal pattern may deserve attention.
For example, a person who previously used the bathroom every three or four hours may suddenly feel the need to urinate every hour.
They may also find themselves making repeated trips to the bathroom despite drinking their usual amount of water.
Sometimes, only a small amount of urine comes out each time.
This can happen because a tumor or irritation inside the bladder affects the normal functioning of the organ. The bladder may become more sensitive, creating the sensation that it needs to empty even when it contains relatively little urine.
The person may begin planning daily activities around bathroom access.
Long journeys become inconvenient. Meetings are interrupted. Shopping trips require frequent stops. Sleep may also become disturbed if the urge to urinate repeatedly wakes them during the night.
At first, people may blame these changes on drinking too much water, consuming coffee, aging, or having a naturally small bladder.
These explanations can sometimes be correct.
Frequent urination is also common in people with diabetes, urinary tract infections, overactive bladder, pregnancy, and prostate enlargement.
But when urinary frequency is new, persistent, unexplained, or accompanied by blood in the urine, it should not be ignored.
Pay attention to changes such as:
-
Needing to urinate much more often than before.
-
Passing only small amounts of urine each time.
-
Waking repeatedly during the night to urinate.
-
Feeling that normal bathroom habits have changed significantly.
-
Experiencing urinary frequency together with blood or discomfort.
The symptom alone cannot establish a diagnosis.
A medical evaluation can help determine whether the problem is related to infection, bladder irritation, medication, metabolic conditions, or another cause.
CHAPTER 4: SYMPTOM NUMBER THREE — A SUDDEN, URGENT NEED TO URINATE
Frequent urination and urinary urgency may sound similar, but they describe two different experiences.
Frequency refers to needing to urinate more often than usual.
Urgency describes a sudden, strong sensation that you must urinate immediately.
A person experiencing urgency may feel that they cannot comfortably postpone going to the bathroom, even when their bladder is not full.
The sensation can be surprisingly intense.
Someone may be sitting at home, working at a desk, or watching television when a sudden urge appears. They may feel compelled to stand up and reach the bathroom immediately.
Sometimes, the urgency returns shortly after they have just urinated.
This can be frustrating and disruptive, especially when it occurs repeatedly throughout the day.
Bladder cancer can cause irritation of the bladder lining, which may contribute to these sensations.
However, urinary urgency is not specific to cancer. It is more commonly associated with conditions such as urinary tract infections, overactive bladder, bladder inflammation, and certain neurological problems.
In men, prostate enlargement may also contribute to changes in urinary habits.
The important question is whether the symptom represents a new or unusual change.
Consider seeking medical advice if you experience:
-
A sudden, persistent need to urinate.
-
Urgency even when very little urine is present.
-
Repeated urgent bathroom visits throughout the day.
-
Urgency combined with burning or blood in the urine.
-
A change that continues despite normal fluid intake.
Do not attempt to solve persistent urgency simply by severely restricting water consumption.
Dehydration can create additional health problems and does not address the underlying cause.
Instead, discuss the symptoms with a healthcare professional.
A urine test and other examinations may help identify the source of the irritation.
CHAPTER 5: SYMPTOM NUMBER FOUR — BURNING, PAIN, OR DISCOMFORT WHEN URINATING
A burning sensation during urination is commonly associated with urinary tract infections.
It is also one of the symptoms that may occur in people with bladder cancer.
The discomfort may feel like stinging, burning, or irritation as urine passes through the urinary tract.
Some people describe a sharp sensation near the end of urination. Others experience a persistent feeling of irritation around the bladder or urethra.
Because urinary infections are common, many people immediately assume that an infection is responsible.
In some cases, that assumption is correct.
A urinary tract infection can cause burning, urgency, frequency, lower abdominal discomfort, and cloudy or strong-smelling urine.
But persistent urinary symptoms should not automatically be attributed to infection.
Bladder cancer can sometimes irritate the bladder lining and produce similar symptoms.
This is especially important when a person experiences repeated urinary problems without a clear explanation, or when symptoms continue despite appropriate treatment for an infection.
For example, imagine someone who develops burning during urination and visits a clinic. They receive treatment for a suspected infection, but the discomfort returns shortly afterward.
They may assume that the infection has not completely disappeared and continue postponing further investigation.
If symptoms persist or recur, the diagnosis should be reassessed.
A healthcare professional may recommend another urine test, a urine culture, or additional examinations to investigate the cause.
It is important not to repeatedly take antibiotics without medical advice. Antibiotics are useful for bacterial infections, but they do not treat bladder cancer and should not be used unnecessarily.
Seek medical evaluation if burning or pain during urination is persistent, recurrent, or accompanied by blood in the urine.
Also seek urgent medical attention if urinary symptoms occur with fever, chills, severe pain in the side or back, vomiting, or an inability to urinate. These symptoms may indicate another serious urinary problem requiring prompt treatment.
CHAPTER 6: SYMPTOM NUMBER FIVE — UNEXPLAINED PAIN IN THE LOWER ABDOMEN, PELVIS, OR BACK
Pain in the lower abdomen, pelvis, or back is another possible symptom associated with bladder cancer.
However, it is important to understand that this is not usually the most characteristic early warning sign.
Many people experience lower abdominal or back pain for reasons unrelated to cancer, including muscle strain, digestive problems, kidney stones, urinary infections, and spinal conditions.
When bladder cancer causes pain, the location and severity may vary.
