Treatment of Skin Cancer in Dogs

The treatment of skin cancer in dogs depends on the type, stage, and location of the cancer. Treatment options may include:

• Radiation therapy: Radiation therapy uses high-energy X-rays or gamma rays to kill cancer cells.
• Chemotherapy: Chemotherapy uses drugs to kill cancer cells.
• Immunotherapy: Immunotherapy uses the body's own immune system to fight cancer.
