Thanks for the info Cheryl. I spoke with my fiance about it. She is a medical scientist, currently doing her pHd. She was quite good at explaining a few things to me and that the chances of me having HPV related throat cancer are extremely low. She even referred me to CDC data on HPV cancers. See here:

Like you explained she also explained that HPV related cancer take time to manifest. Though she said it takes along time to cascade to cancer. She also said that though they find HPV in tumors and call it HPV cancer it is likely that there are other contributing factors (not yet known) that create the environment for the tumor to form.

The ENT at the hospital actually phoned me this morning and told me there was no abnormalities on the MRI which I was told was very reassuring and if there was something the chances it was missed are very low. He did say I obviously have an issue and the cause needs to be found. I guess I will have to keep at it until diagnosed

The hospital ENT told me to keep my appointment with with the another ENT I made a few weeks back which happens to be his boss.

Things seems to be looking positive so far. Will keep this thread updated as things progress.

Thanks so much for your support
