I am trying to get some info for my sister. Her 5 year old golden retriever was just diagnosed with a Grade 2 mast cell tumor located on her side. They removed the tumor but have now told her they need to do more surgery since the margins are not clean. She is going to a specialist this week. This is her first tumor. The biopsy says it is a Grade 2 with a MI of 0. I am not sure what that means. What is the protocol for treating this? What should my sister be doing to help Daisy. She is only 5 years old?
