There are Four main types
of lymphoma that affect our canine companions, while there are over 30 different types these are the most prevalent. All types of lymphoma have different aggressions, survival rates, as well as symptoms.
Multicentric Lymphoma: This is the most common type of lymphoma found in dogs. Almost all lymphoma found in dogs is multicentric, making up approximately 85% or all lymphoma cases found in dogs are multicentric. Multicentric lymphoma affects the lymph nodes when cancer is in the lymph nodes it causes excessive swelling and enlargement of the lymph nodes.
Alimentary Lymphoma: This is the second most prevalent type of lymphoma found in canines. Accounting for under 10% of all lymphoma cases it is a cancerous manifestation in the lymphatic system targeting the intestines, where most if not all of the symptoms of this cancer manifest.
Extranodal Lymphoma: This is a variation of lymphoma where cancer chooses to manifest in a specific organ. For example, it may target the skin, kidneys, lungs, eyes, or central nervous system. The most common subcategory of this extranodal lymphoma is cutaneous lymphoma which targets the skin.
Mediastinal lymphoma: This is a very rare version of lymphoma, in this case, either both the mediastinal lymph nodes and thymus become enlarged. This is due to a malignant t-lymphocytes, where tumors eventually form and need to be treated immediately.
