Prayers Needed!

Just before we left Canada we noticed a golf ball size lump on our golden retriever Wookie's left side.  We consulted with our vet in Rockwood and he advised us to "just go to Mexico and deal with it there"as Wookie required an international health certificate stating he was in excellent health.
Since we have been here, the lump has grown - we have consulted with two different vets here who have both come highly recommended to us by friends.  After the first consultation, vet #1 told us that he was pretty sure it was a form of cancer and that surgery should be done to remove the mass.  We decided on a second opinion.  Vet #2 also was certain that it was a form of cancer, however he has suggested a different approach.  He administered a mega shot of anti-inflamatory and a mega shot of anti-biotics.  Wookie goes back in on Monday afternoon for a biopsy of the tissue.  He will be put under for this proceedure.  Once the results are back from the lab, we will then know have to decide on how to proceed.  Chemo will be an option if the cancer (either mast cell tumor or lymphoma) has not spread to other organs. We will do whatever is best for Wookie.
To say I write this with a heavy heart is an understatment.  Both Greg and I are terribly upset but we are both trying to keep positive until the test results are presented. 
Apparently, both these types of cancer are common in Golden Retrievers and tend to show up around 7 years of age.  Wookie will be 7 in September.
Please say a little prayer for our "best pal" - our "job dog" (his nickname)
Will keep you all posted...........
