The most
common type of bladder cancer found in dogs is Transitional Cell Carcinoma
(TCC).
TCC is an
aggressive malignant cancer that invades the bladder walls causing obstruction
to the urinary tract which in turn affects the natural flow of the urine. The
cancer will normally spread to the lymph nodes and to other organs such as the
lungs and liver.
Symptoms of Bladder Cancer in Dogs
Symptoms of
bladder cancer in dogs often go undetected for months and are normally mistaken
as urinary tract infections. The symptoms of canine bladder cancer include:
- Blood in
the urine
- Difficult
and painful urinating
- Coughing
and breathing difficulties
- Increased frequency of urinating
-
Incontinence urinating
- Smaller
amounts of urine are passed
- Recurring
urinary tract infections
If your dog
shows the symptoms above, ask for extra tests to be done just in case it is
cancer.
Treatment for Bladder Cancer in Dogs
Surgery:
Surgery is
often not considered unless there is a tumour that is of size and localized. In
the case of TCC, surgery is unlikely to be effective as the entire bladder wall
is affected and the cancer will often reoccur after surgery.
Medications:
Intravenous chemotherapy
with a drug called Mitoxantrone is usually the most effective treatment for
dogs with bladder cancer. Non-steroidal, anti-inflammatory drugs such as Piroxicam
are taken orally along with the chemotherapy to try to stabilize and shrink the
tumours. Piroxicam alone has is capable improving and extending the lifetime of
the affected dog and also provides relief of bladder pain.
Radiation Therapy:
Radiation
therapy can be quite effective over a long period of time. Small amounts of
radiation are induced each day over a 3 – 4 week period. It is often used after other therapies as a
method to destroy the last remaining cancerous cells.
The most common gall bladder symptoms is pain or tenderness in the abdomen, which may occur just after eating.
