Understanding Cancer in Pets
Cancer is one of the most common health concerns in pets, particularly as they age. While a diagnosis can be daunting, advancements in veterinary oncology offer hope. Many cancers are treatable, allowing pets to continue living happy, fulfilling lives with the right care plan.
Common Types of Cancer in Pets & Symptoms to Watch For
Pets can develop various types of cancer, including:
Lymphoma – A cancer of the lymphatic system, often causing swollen lymph nodes.
Mast Cell Tumors – Skin tumors that may appear as lumps, sores, or red, inflamed areas.
