Lymphoma in Cats
Lymphoma is the most common malignancy diagnosed in cats. Lymphoma in young cats occurs most frequently following infection with feline leukemia virus (FeLV) or to a lesser degree feline immunodeficiency virus (FIV). These cats tend to have involvement of lymph nodes, spine, or mediastinum. Cats with FeLV are 62 times more likely to develop lymphoma, and cats with both FeLV and FIV are 77 times more likely. Younger cats tend to have T-cell lymphoma and older cats tend to have B-cell lymphoma. Older cats tend to have gastrointestinal lymphoma without FeLV infection, although tests more sensitive to low level FeLV infections and replication-defective FeLV have found that many of these cats have been previously exposed. The same forms of lymphoma that are found in dogs also occur in cats, but gastrointestinal is the most common type. Lymphoma of the kidney is the most common kidney tumor in cats, and lymphoma is also the most common heart tumor.
