For a little bit of background context, my dad has always struggled with ENT problems - blocked ears, throat infections, sore eyes, ears! He is definitely prone to these types of infections and when he get's poorly he gets really poorly. The last time he had any throat issue it was Quincey that he had drained and was given antibiotics. 

So up until last week he was okay but woke up with a lump on his tonsil and a coarse voice - he had no other symptoms but because it was the weekend he just took some penicillin he had at home and it helped ease his symptoms, he took these until the following Wednesday and was doing well until he ran out and woke up on the Thursday morning just as bad and with a big lump near his tonsils/top of mouth. He went to the GP who referred him straight to hospital with suspected Quincey again, we didn't worry too much about this as we thought it would mean he would have his tonsils drained and antibiotics would be supplied. But once reaching the hospital, the DR there wanted a second opinion, the consultant confirmed that he wasn't happy with what he was seeing and would like to refer him for an urgent MRI and Biopsy. This was a week ago and the two tests will be taking place tomorrow and Friday. Since then the lump has gone down on some days and risen again on other and we all are just so worried at what this could be. He has no other symptoms, and the symptoms he does have, appeared quite quickly. 

Has anyone had anything similar? Do you think if they thought it was something sinister they would have had the biopsy and MRI done at the hospital when he was there? Has anyone been through anything similar. 

My dad is in his 60's and otherwise fit and healthy.
