Rabbit Lumps and Bumps: Abscesses, Tumors, Cysts & Health Risks

Any lump or growth found on a rabbit—whether from an abscess, cyst, benign swelling, or a possible tumor—should always be examined by a veterinarian, as early diagnosis is essential for proper treatment and long‑term health.

5 Common Causes of Lumps in Rabbits

• Abscesses: Often caused by bacterial infections; filled with pus and may feel firm under the skin.

• Cysts: Fluid‑filled sacs that can develop in various tissues; usually benign but may grow.

  
  

• Lipomas: Non‑cancerous fatty tumors; can become large enough to affect mobility.

  
  

• Cancerous growths: Malignant tumors such as carcinomas or sarcomas; early diagnosis is critical for treatment.
  

• Myxomas: Rare but serious viral‑related tumors seen in rabbits.

  
  
  
  

What You Should Do

• Seek veterinary care: Any lump should be examined promptly to determine the cause.

  
  

• Never attempt home treatment: Abscesses and tumors require professional diagnosis and care.

  
  

• Monitor changes: Note size, texture, and whether the lump grows or causes discomfort.

  
  

• Check overall health: Watch for weight loss, lethargy, or changes in appetite, which may signal a serious issue.
