My golden retriever, Honey, recently turned 9 years old and recently had a Mast Cell tummor removed from her mouth. She recovered fine initially but unfortunately, the cancer had spread to her lymph node in her throat and has grown to the size of a tennis ball. She received a chemotherapy dose three weeks ago, but the tumor appears to have grown larger and in the past couple of days she has had trouble eating. Are there any reccommended therapies out there for lymph node cancer? Thanks.
