This is going to sound stupid probably, but I don't quite grasp how T2 develops from having had cancer? It's genetic for the most part, unless brought on by steroids, statins or other medication. (The cancer itself could be relatively innocent in this case, the treatment of it, however?) Unless you had pancreatic cancer, then it'd be type 3, not two... And that might require a different treatment, depending on how much insulin you still make. Just putting it out there, in case your treatment depends on it, it's stuff to ask the nurse about? Maybe, if there's a question of insulin production versus insulin sensitivity, you might want to ask for a C-peptide test to make sure they're not barking up the wrong tree. You've already gotten the link to The Nutritional Thingy, so you already know how to tackle dietary control of T2, but to be on the safe side, here it is again:
https://www.diabetes.co.uk/forum/blog-entry/the-nutritional-thingy.2330/ So what can you expect.... Right now, with covid in the mix, I don't quite know. Normally you'd get a once-over, check heart, blood pressure, get a foot check, and probably get an eye-check done as well. Get on the scales, that sort of thing. Maybe more bloodwork for kidney and liver function, as well as cholesterol, unless that was done recently already. At the mo, no clue what all of that is done right now. But just make a list of all the things you want to ask the nurse, and make sure to bring a pen to note down the answers. And request all your test results, if you can't access them online already. (Some practices offer that service).
Good luck!
