Dear Donna,
I am sorry to hear about the lymphoma which Nikki has. Benny was also on prednisone towards the end of his cancer and it helped a lot to shrink the early tumours. Yes, there is much information here and you might also find out more on a website which I used called
The Smiling Blue Skies Cancer Fund - smilingblueskies.com which was started by a friend who lost her 6 year old Golden Retriever to lymphoma in 2001.
You will be in my prayers.
Joanne
