Subject: Re: Question about Lymphoma in groups
             Betty, there is the possibility that there might be a viral trigger 
for lymphoma.  Two things that make it difficult to figure out are: 
if there is one then the virus may be silent enough that exposure 
would not be known, and secondly that it is very difficult to find 
such triggers so such investigations may take years.  There was 
project at the Dept. of Comparative Medicine of MIT trying to find 
one in ferrets, but I believe that it had to stop after a while.
We, too, have had it in groupings here in our home, and I am very 
sorry that you had to experience this.
