Canine and Feline Lymphosarcoma
Lymphosarcoma is a malignant cancer of the lymph nodes and lymphoid tissue that affects both dogs and cats, most often dogs over four years of age. It presents in multicentric, alimentary, and thymic forms, each with distinct clinical signs. While incurable, prompt chemotherapy can extend life from a matter of weeks to 6–24 months.
Canine and Feline Lymphosarcoma (Lymphoma)
Lymphosarcoma, also called lymphoma, is a malignant tumor of lymphocytes that arises in lymph nodes or other lymphoid tissue. It occurs in both dogs and cats, more often in dogs over about 4 years, and appears as multicentric, alimentary, or thymic forms with enlargement of lymph nodes, digestive upset, or chest masses.
Canine and Feline Spinal Cord Tumors
Spinal cord tumors in dogs and cats produce signs based on where they compress the cord, ranging from limb weakness to paralysis and loss of bladder control. German Shepherds and young to middle-aged dogs are commonly affected, with tumors often located between the 10th thoracic and 3rd lumbar vertebrae.
Canine and Feline Brain Tumors
Brain tumors in dogs and cats are most often meningeal or glial tumors that appear in middle-aged to older pets, with some breeds such as Boxers and Bulldogs overrepresented. They compress brain tissue and cause gradually worsening neurological signs including behavior changes, circling, head tilt, blindness, and seizures.
Canine and Feline Hemangioma and Hemangiosarcoma
Hemangiomas are slow-growing benign tumors of blood vessels, while hemangiosarcomas are aggressive malignant vascular tumors that often spread before signs appear. Common sites include the skin, spleen, liver, heart, and bone, with large breeds such as Great Danes, Boxers, and German Shepherds overrepresented.
Canine and Feline Ovarian Tumors
Ovarian tumors are uncommon in dogs and cats and usually arise as a primary growth, most often a granulosa cell tumor in older females. Hormone-secreting types cause persistent estrus, while others simply enlarge the abdomen; surgery is typically curative.
Canine and Feline Renal Adenoma and Kidney Tumors
Kidney tumors in dogs and cats may be primary growths such as renal adenoma or nephroblastoma, or spread from cancers elsewhere — metastatic kidney tumors are actually more common. Signs are vague but include weight loss, abdominal swelling, and changes in urination.
Canine and Feline Pancreatic Tumors
Pancreatic tumors occur in older dogs and cats and can be benign or malignant; many spread widely, especially to the liver. Insulin-secreting tumors cause low blood sugar, while surgical removal offers the best chance when caught early.
Canine and Feline Splenic Tumors
Splenic tumors in dogs and cats may be primary or spread from other sites, and often stay silent until the spleen is already enlarged, causing bloating, pain, or anemia. Hemangiosarcoma can rupture and bleed dangerously, making prompt care essential.
Canine and Feline Liver Tumors
Liver tumors in dogs and cats may be primary or spread from elsewhere, with signs much like chronic liver inflammation — poor appetite, weight loss, and vomiting. Slow-growing tumors confined to one lobe can often be removed surgically.
