Lymphosarcoma is the third most common cancer found in dogs. It’s present in lymphocytes and lymphoid tissues which are located in many parts of the body including lymph nodes, liver, bone marrow and the spleen.
The average age of sufferers is 6-9 years, but dogs of any age can be affected and certain breeds like the German Shepherd, Scotties, Westies and Pointers are more susceptible.
There are 5 types of Lymphosarcoma which are determined by the location of the tumour. These types are external lymph nodes, bone marrow, skin, gastrointestinal tract and mediastinal.
There are a whole host of methods for diagnosis due to the multiple areas in which Lymphosarcoma can be found. Tests include a biopsy of affected tissue, a complete blood count, an abdominal ultrasound and x-rays.
Lymphosarcoma can be treated with surgery and chemotherapy, with up to 80% of dogs treated going into remission. Although it’s not a cure, it does allow the dog to have a good quality of life for an average remission time of 8-10 months.
