Bovine Leukemia (Lymphoma)

21.3.3 Bovine Leukemia (Lymphoma)

In certain countries, bovine leukemia is one of the most common types of cancer in livestock. It is caused by a virus and can be spread throughout a herd by injecting many animals with the same syringe and needle. Symptoms are often vague and general, making the problem difficult to diagnose. Affected animals may have enlarged lymph nodes and may become frequently ill. There is no treatment.
