What Are Canine Tumors?

Tumors in dogs are abnormal growths of cells that can be benign (non-cancerous) or malignant (cancerous). While benign tumors generally grow slowly and do not spread, malignant tumors can invade nearby tissues and metastasize to other parts of the body.

Lipoma	Fatty, soft lumps under the skin	Chest, abdomen, limbs	Low
Mast Cell Tumor	Can vary in appearance; may be itchy or swollen	Skin, especially trunk	High
Melanoma	Dark pigmented tumors, often on mouth or skin	Mouth, skin, digits	Variable
Osteosarcoma	Bone cancer causing lameness and swelling	Limbs	High
