Companion Golden Retriever Rescue

Recent studies show that 1 in 5 Golden Retrievers will develop a malignant cancer called hemangiosarcoma. Discover how non-invasive abdominal ultrasound can detect this common and serious splenic cancer without anesthesia or pain early in high-risk patients over age 5.

Golden Retrievers have long been known as the most common breed for developing a silent form of cancer called hemangiosarcoma. Until recently, the actual seriousness of the genetic potential for this disease was not fully appreciated. New studies have found that 1 in 5 Golden Retrievers will develop this malignant form of cancer that most commonly presents in the spleen. In addition, 1 in 8 Golden Retrievers will develop another form of malignant cancer called lymphosarcoma. Due to the nature of splenic cancer, it is a silent disease that does not appear on routine senior blood work screening like other senior illnesses such as liver or kidney disease.

Symptoms of splenic cancer in golden retrievers

Most commonly, patients with splenic cancer have NO symptoms until the situation is dangerous. 50% of tumors that grow on the spleen are malignant, and the other 50% can still be life-threatening benign tumors due to the size that can be obtained (many times softball to grapefruit sized or larger at discovery) and the risk for sudden rupture and fatal hemorrhage. When subtle signs do occur, most often a decreased appetite, slight slowing down or decreased activity, or perhaps a mild anemia on bloodwork is observed. On occasion, a mild elevation of liver enzymes can occur if pressure on the adjoining liver lobes is occurring or disruption of blood supply due to physical changes by the tumor in the abdomen.
