I always close my eyes when taking the MRI, CT or PET. I do think its a tube, but not as small as the MRI.

Excellent question about MM! I have read from Gary about being cautious not to swallow magic mouthwash while others have said its perfectly ok to do. When I went thru it the first time I would do the MM and then take my pain meds. It made them easier to swallow. Ive seen several others do it as well. With your recent surgery, I cant imagine how it would feel attempting to swallow anything. Many meds can be bought in liquid form which makes them much easier to take. If necessary ask your docs for prescriptions to get them in liquid form. They are more expensive like that but insurance will cover them.

A tumor of 1.5 mm is tiny! Hopefully that means your cancer was found early at Stage I. Oral cancer commonly will jump over into the lungs. Many of us have had 'spots' on our scans for years which go unchanged so if something shows, dont panic. Ive had a 2mm 'spot' for the past 3 or 4 years and Ive quit worrying about it.

Try to rest and keep your mind occupied so you dont go to the "what if's" of worrying. Take it step by step, day by day and dont get ahead of yourself. I have been down this path twice and know how hard it is. Try reading something interesting which keeps you focused.

Good luck with yorur recovery!
