Spleen tumor may not be malignant
The Expert Vet (10-26-2015) #5056: Have an older dog with a tumor on his spleen? Do not despair! And do not rush to that conclusion. Many vets assume these tumors are cancerous, but many are not — they are benign tumors that are treatable! Dr. Donna tells a story with a happy ending about Rocko, a 12 year old Golden Retriever who had a huge mass on his spleen. Luckily his people went to Donna for an opinion before putting him to sleep, as their vet recommended. Lo and behold it was a benign mass and Rocko responded well to medical management and he is alive, well and enjoying life with them!
