When Cancer Strikes the Blood Vessels of Older Dogs
An all-too-common disease of older dogs
There are six types of cancer that make up the majority of malignancies striking older dogs: lymphoma (cancer of the lymph nodes), osteosarcoma (bone cancer), mammary cancer, mast cell tumors (mast cells are immune cells found all over the body), soft tissue sarcoma (cancer that takes hold in connective tissue like muscles and nerves), and one called hemangiosarcoma. Hemangiosarcoma, with its grim prognosis, may be the diagnosis a dog owner least wants to hear. Chris Stickell of Monkton, Maryland, has now heard it twice — first with one of her golden retrievers, and then with another one from the same line, 10-year-old Bailey.
