Uterine adenocarcinoma in rabbit

Uterine Adenocarcinoma in Rabbits
Introduction Uterine adenocarcinoma is the most common type of cancer found in female rabbits. It is a malignant tumor of the uterine lining that can spread (metastasize) to other organs, such as the lungs, liver, and bones, if not detected and treated early.

Risk Factors

Age: This is the most significant risk factor. The incidence of uterine cancer increases dramatically as rabbits age. It is found in over 50-80% of unspayed female rabbits over the age of 3-4 years.
Hormones: Continuous exposure to reproductive hormones in intact (unspayed) females is the primary driver of this disease.
Clinical Signs In the early stages, rabbits may not show any symptoms. However, as the disease progresses, owners may notice:

Hematuria or Vaginal Discharge: Blood in the urine or bloody discharge from the vulva (often mistaken for normal urine but appears as distinct blood spots).
Aggression or Behavioral Changes: Due to discomfort or hormonal imbalances.
Mammary Gland Changes: Cysts or tumors in the mammary glands (often occur concurrently).
Lethargy and Weight Loss: In advanced or metastatic cases.
Difficulty Breathing: If the cancer has spread to the lungs.
Diagnosis Veterinary diagnosis typically involves:

Physical Examination: Palpating the abdomen to check for an enlarged uterus or masses.
Imaging: X-rays or Ultrasounds to visualize the uterus and check for metastasis in the chest/lungs.
Blood Work: To assess overall health and organ function.
Biopsy/Histopathology: Confirming the cancer type after surgical removal.
Treatment

Ovariohysterectomy (Spaying): This is the primary treatment. Surgical removal of the ovaries and the entire uterus is curative if the cancer has not yet spread beyond the uterus.
Supportive Care: Pain management and fluid therapy may be required during recovery.
Prevention The most effective way to prevent uterine adenocarcinoma is to spay (sterilize) female rabbits at a young age, typically between 4 to 6 months. This completely eliminates the risk of developing uterine cancer and other related uterine diseases.
