When cells grow out of control, the body’s balance is disrupted.
Cancer
Cancer in dogs refers to uncontrolled growth of abnormal cells that invade or spread within the body. It can affect virtually any tissue, including skin, lymph nodes, bones, and internal organs.
Common cancers in dogs include lymphoma, mast cell tumours, osteosarcoma, hemangiosarcoma, and mammary gland tumours. Age, genetics, and environmental factors contribute to risk.
Cancer is not a single disease – it is many conditions with one common feature: unregulated cell growth.
Core signs of Cancer include:
- Unexplained lumps or swellings
- Weight loss and decreased appetite
- Lethargy or weakness
- Persistent sores or wounds that don’t heal
- Coughing, lameness, or bleeding depending on tumour location
While not all cancers are curable, early detection, surgery, chemotherapy, and supportive care can greatly extend life and improve wellbeing.
