🐾 Mammary Tumours & The Importance of Spaying 🐾
Since opening our doors at Ste. Anne Veterinary Hospital, we’ve unfortunately seen quite a few dogs diagnosed with mammary tumours. While some mammary tumours are benign, many can be malignant (cancerous) and have the potential to spread to other parts of the body.
One of the most effective ways to reduce the risk of mammary tumours is by spaying female dogs before their first heat cycle. The protective effect decreases with each heat cycle, meaning early spaying can dramatically lower the risk of developing these tumours later in life.
🔹 Mammary tumours often start as small lumps along the mammary chain.
🔹 Early detection and treatment can improve outcomes.
🔹 Regularly feeling for new lumps at home is important, especially in unspayed females.
If you notice any new lumps or bumps on your pet, don’t hesitate to have them checked. Not every lump is cancer, but early diagnosis gives us the best chance of successful treatment.
Have questions about spaying or a lump you’ve found on your pet? We’re happy to help.
