Mammary cancer

Cancer of the mammary glands

Mammary cancer can cause a variety of symptoms in pets. Common types of mammary cancers include adenomas, benign mixed tumors, mammary carcinoma or adenocarcinoma, and mammary fibrosarcoma. Signs may include:

  • Lumps or swelling in the mammary glands or surrounding areas that may vary in size and feel firm or irregular
  • Discharge from the nipples, such as blood or pus
  • Ulceration or redness of the mammary glands
  • Pain or discomfort when touching or palpating the mammary glands
  • Loss of appetite or decreased food intake
  • Unexplained weight loss
  • Lethargy or decreased activity level
  • Difficulty breathing or a persistent cough

Other health conditions may share similar symptoms with mammary cancer, including mammary gland infections, benign mammary tumors, or hormonal imbalances.

If you notice any of these signs or if you have concerns about your pet's health, it's essential to consult with your veterinarian. Early detection and intervention can improve the chances of successful management and improve your pet's quality of life.

When you visit the veterinarian for concerns related to mammary (breast) cancer, the following may occur:

  • Physical examination: The veterinarian will perform a thorough physical examination of your pet, including palpating the mammary glands and checking for any abnormalities or palpable masses.
  • Diagnostic testing: Blood tests, imaging (such as X-rays or ultrasound), fine-needle aspiration, or biopsy may be recommended to evaluate the presence and extent of the cancer. These tests help determine the type, stage, and characteristics of the cancer.
  • Treatment options: Treatment for mammary cancer can vary depending on the specific type, location, and stage of the cancer. More aggressive options may include surgery to remove the tumors and affected mammary glands, radiation therapy, chemotherapy, or a combination of these approaches. Palliative care, focused on managing symptoms and improving quality of life, is also an important consideration for pets with cancer.
  • Advanced diagnostic or treatment options: Referral to a veterinary oncologist or veterinary surgeon may be advised for specialized diagnostic or treatment options.
  • Follow-up care: Based on your goals, you and your veterinarian will create a follow-up plan, which may involve regular monitoring, additional tests, or adjustments to the treatment plan. It’s crucial to maintain open communication with your veterinary care team throughout the process about how you and your pet are doing.

The decision regarding treatment options should be made in partnership with your veterinary care team, considering your pet's and family’s individual circumstances and well-being.

There are limited specific measures to prevent mammary cancer in pets. However, there are steps you can take to promote overall health and potentially reduce the risk of certain cancers:

  • Spaying or neutering: Spaying your female pet at an early age, before her first heat cycle, significantly reduces the risk of mammary cancer. Consult with your veterinarian regarding the appropriate timing for the procedure.
  • Maintain a balanced diet: Specific diets may be recommended to help manage health risks, so talk to your vet about your pet's particular health needs to ensure they are getting well-balanced nutrition.
  • Weight management: Obesity has been linked to an increased risk of cancer in pets, so maintaining a healthy weight is important. Provide regular exercise and appropriate environmental enrichment for mental stimulation to keep your pet physically active and mentally engaged.
  • Environmental safety: Minimize exposure to environmental toxins and hazardous substances that may contribute to the development of cancer. Keep your pet away from cigarette smoke, chemical cleaners, pesticides, and other potentially harmful substances.
  • Cancer screening or genetic testing: For pets with a higher predisposition to specific types of cancer, cancer screening or genetic testing may be available. Consult with your veterinarian to determine if testing is appropriate for your pet.
  • Early detection and intervention: Be vigilant in observing any changes in your pet's behavior, appetite, or overall health. In addition to routine veterinary checkups, seek veterinary attention promptly for evaluation and potential early intervention if you notice any concerning signs or symptoms.
