Thanks for all your concern. Sam is currently still in the hospital, the vet has just called to say, that part of the mass in the rectum area was an abcess, that burst when they put the needle in to take a sample and reduced the mass in size, whilst they were carrying out the tests. They also found some of the other lymph nodes in the abdoman to be swollen. We are still waiting to find out if there is any cancer or not. We will not know anything more until tomorrow. However Sam has settled in well at the hospital, so hopefully he will have a good night & will be well looked after and hopefully we will have him back home tomorrow - so we can spoil & pamper him.
