HEMANGIOSARCOMA
This cancer is somewhat common in dogs and more so in certain breeds
including German Shepherds. The tumor most often appears on the spleen or
the heart although varieties also appear on the skin or in other locations.
LYMPHOMA
Lymphoma is the third most common cancer diagnosed in all dog
breeds. It is a cancer of lymphocytes (a type of blood cell) and lymphoid
tissues. Lymphoid tissue is normally present in many places in the body
including lymph nodes, spleen, liver, gastrointestinal tract and bone
marrow.
OSTEOSARCOMA
Osteosarcoma, a type of bone cancer, may be on the rise in Irish setters. It
commonly is found in the dog’s limbs, although it may also be found in the
shoulder, and secondary tumors may appear in the pelvis and other bone
tissue, as well as the lungs. Most Irish setters who are affected develop
the disease between seven and ten years of age. In some early cases,
metastasis may be slowed by amputation of the affected limb and following
with a course of chemotherapy.
