Testicular cancer

What are the causes of testicular cancer in dogs?

The exact cause of testicular cancer in dogs is not known, but there are some factors that may increase the risk. These include:

• Age: Testicular cancer tends to occur in older dogs, especially after the age of seven.
• The breed : Some breeds are more prone to testicular cancer than others, for example Boxers, German Shepherds, Poodles and Terriers.
• The location of the testicles: Dogs that have one or both testicles in the abdomen (cryptorchidism) have a higher risk of testicular cancer than dogs whose testicles have descended normally into the scrotum.

What are the symptoms of testicular cancer in dogs?

The symptoms of testicular cancer in dogs can vary depending on the type and stage of the tumor. Some of the most common symptoms are:

• An enlargement or swelling of one or both testicles
• A change in the shape or consistency of the testicles
• Pain or discomfort in the area of the testicles
• Blood in the urine or semen
• Loss of appetite, weight loss or lethargy
• Behavioral changes such as aggressiveness, depression or increased marking
• Signs of femininity such as enlarged mammary glands, hair loss or reduced interest in females

How is testicular cancer diagnosed in dogs?

To diagnose testicular cancer in dogs, your vet will perform a physical examination and palpate the testicles. He will also order a blood test to check hormone levels and rule out other diseases. To determine the type and extent of the tumor, your vet may also perform an ultrasound scan, an x-ray or a biopsy of the testicles.

How is testicular cancer treated in dogs?

The treatment of testicular cancer in dogs depends on the type and stage of the tumor. The most common treatment is castration, i.e. surgical removal of the testicles. This can completely remove the tumor or at least slow down its growth. In some cases, your vet may also recommend chemotherapy or radiotherapy to combat any metastases. The prognosis for dogs with testicular cancer is usually good if the tumor is detected and treated early.

How can you prevent your dog?

The best way to prevent testicular cancer in dogs is to neuter them at a young age. This can reduce the risk of testicular cancer by up to 90%. If you don't want to neuter your dog, you should check his testicles regularly for changes and have him examined by a vet at least once a year. If you notice any signs of testicular cancer in your dog, you should not hesitate to contact your vet.
