Mammary Tumors in Dogs: Care and Considerations173

Mammary tumors are among the most common tumors found in female dogs, affecting approximately 50% of unspayed females over the age of 10. These tumors can develop in a single mammary gland or multiple glands simultaneously. Understanding the types, signs, and treatment options for mammary tumors is crucial for providing the best possible care for your beloved dog.

Types of Mammary Tumors

Mammary tumors are classified based on their cellular characteristics:
Benign tumors: These tumors are non-cancerous and do not spread to other parts of the body.
Malignant tumors: These tumors are cancerous and have the potential to spread and metastasize to other organs.

The most common type of malignant mammary tumor in dogs is adenocarcinoma, which accounts for approximately 85% of cases.

Signs of Mammary Tumors

Mammary tumors typically manifest as palpable lumps or bumps in the mammary glands. Other signs may include:
Changes in the size, shape, or texture of mammary glands
Inflammation or redness of mammary glands
Ulceration or discharge from mammary glands
Loss of appetite
Lethargy
Rapid breathing or coughing (if the tumor has spread to the lungs)

Diagnosis

If you suspect your dog has a mammary tumor, it is essential to consult your veterinarian promptly. Your veterinarian will perform a physical examination and may recommend additional tests, such as:
Fine needle aspiration (FNA): A biopsy technique where a thin needle is inserted into the tumor to collect cells for microscopic examination.
Mammogram: An imaging technique that uses X-rays to visualize mammary tumors and determine their size and location.
Ultrasound: An imaging technique that uses sound waves to visualize mammary tumors and assess their internal structure.

Treatment Options

The appropriate treatment for a mammary tumor depends on various factors, including the tumor's type, size, location, and the dog's overall health.
