1. What are the causes of bladder cancer in cats?

Although the exact causes of feline bladder cancer are not always clear, several risk factors have been identified by veterinary research. It is noted that this disease more frequently affects male cats. Obesity and exposure to certain environmental chemicals are also considered aggravating factors, increasing the likelihood of developing a urinary tract tumor.

2. What is transitional cell carcinoma (TCC)?

Of all diagnosed bladder cancers, between 50 and 70% are transitional cell carcinomas (TCCs) . These aggressive tumors originate in the cells lining the inner wall of the bladder. This type of cancer is particularly concerning because it can obstruct the normal flow of urine.

3. What are the symptoms of bladder cancer?

It is crucial to detect the early signs of a bladder tumor in cats in order to intervene quickly. Here are the most common symptoms:

• Hematuria: Presence of blood in the cat's urine.
• Dysuria: Visible difficulty and straining to urinate.
• Pollakiuria: Frequent urination, but in very small quantities.
• Abdominal pain upon palpation.

4. How can I tell if my cat has cancer or just a urinary tract infection?

Diagnosis is often complex because the symptoms of bladder cancer closely mimic those of a urinary tract infection (cystitis) or bladder stones. If your cat does not respond to standard antibiotics for its urinary problems, further testing (ultrasound, urinary sediment analysis, or biopsy) is necessary to rule out a tumor.

5. What is the life expectancy of a cat with bladder cancer?

When a urinary tract tumor is confirmed, the question of survival is a legitimate one. According to clinical data, the average life expectancy is between 4 and 9 months . However, this prognosis varies considerably depending on the stage of the cancer at the time of diagnosis and the immune support provided.

7. Frequently Asked Questions (FAQ)

Is bladder cancer in cats painful?

Unfortunately, yes. Transitional cell carcinoma (TCC) causes inflammation of the bladder wall and can create painful pressure when trying to urinate. That's why comfort management and immune system support are top priorities in palliative care.

Why does my cat have blood in its urine (hematuria)?

Blood in the urine is a sign that the lining of the bladder or urethra is irritated or damaged. In the case of cancer, the tumor may bleed or cause micro-lesions. Note: this symptom is identical to that of severe cystitis, so veterinary imaging is essential for diagnosis.

Is bladder cancer contagious to other cats or humans?

Absolutely not. Cancer is an abnormal proliferation of cells specific to the individual. There is no risk of transmission to your other pets or family members. You can continue to cuddle your cat without worry.

Can bladder cancer be treated through diet?

Diet cannot "cure" cancer, but it plays a crucial role. A diet rich in high-quality protein and low in simple carbohydrates is recommended, as cancer cells often use glucose as their primary energy source. Adding omega-3 fatty acids can also help reduce systemic inflammation.

What tests are needed to confirm a urinary tract tumor?

The veterinarian usually begins with a urinalysis, followed by an abdominal ultrasound to visualize the bladder wall. In some cases, a veterinary tumor antigen (VBTA) test or aspiration cytology may be performed to confirm the malignant nature of the cells.
