What is lymphoma in a dog?

Lymphoma in dogs is a common cancer of the immune system's white blood cells (lymphocytes) that causes abnormal cell growth, often starting in the lymph nodes but potentially affecting organs like the spleen, liver, or intestines, leading to symptoms such as swollen glands, lethargy, weight loss, increased thirst/urination, and poor appetite, and while not curable, treatment (like chemotherapy) can achieve remission and improve quality of life.
