We decided just to let them remove the lump instead of just getting a needle to be put in and a sample taken because if it was a tumor he would need it removed anyway. Also he had a chest infection through the stress of moving when we got him so no point making him get stressed and another chest infection. It is going to be an extra £50 to get it sent away and checked but it is better than not knowing. To phone at 1 because they aren't busy today. Hopefully they won't phone before then with bad news like what has happened in the past :-\ Will let you know what they say when we phone.
