Like people, pets can develop cancer affecting almost any organ or tissue in their body. The symptoms that may be observed vary based on the organ(s) involved and the severity of the cancer. Here are some possible signs of cancer in pets*:

• Abdominal swelling
• Bleeding from the mouth, nose, or other body openings
• Difficulty breathing
• Difficulty eating
• Lumps, bumps, or discolored skin
• Non-healing wounds
• Persistent diarrhea or vomiting
• Sudden changes in weight
• Unexplained swelling, heat, pain, or lameness
• Visible mass/tumor

Many of the signs seen with cancer are also seen with non-cancerous conditions, but they still need prompt attention by a veterinarian to determine the cause. Cancer is frequently treatable and early diagnosis will aid your veterinarian in delivering the best care possible.
