2. INTRODUCTION
 Dr. Joel Todd Leroy Prince has practiced veterinary medicine for more than
30 years. Board-certified in small animal care, Dr. Joel Todd Leroy Prince
maintains a particular interest in canine cancers, including lymphoma.
Diagnoses of lymphoma make up between 15 percent and 20 percent of
all new canine cancers. Middle-aged and older dogs are particularly
susceptible to the disease, as are golden retrievers, bulldogs, and basset
hounds. Each diagnosis falls into one of four categories.
Approximately 80 percent to 85 percent of dogs with lymphoma develop
the multicentric form of the disease. Tumors in these animals develop on
lymph nodes in different parts of the body. In most cases, the disease
makes itself known when the lymph nodes begin to grow dramatically.

3. LYMPHOMA
 Alimentary lymphoma is the second most common form of the disease,
making up nearly 10 percent of cases. Dogs with this condition develop
tumors in the gastrointestinal tract, which means the majority of
symptoms are digestive.
Extranodal lymphoma develops in a single organ that is not a part of the
lymphatic system. This lymphoma may appear in the lungs, kidneys, eyes,
or the central nervous system, but it most commonly affects the skin,
where it is called cutaneous lymphoma.
The final and the rarest type is mediastinal lymphoma, which affects the
lymph nodes in the chest, the thymus, or both. The disease presents when
the affected organs increase in size.
