Hello, sorry you find yourself here and with the added complication of MG. I don’t have MG myself but I know a bit about it. Not sure show much information there is out there specifically for MG plus cancer, but have you had a look at the MyAware website?
Also, definitely give your neurologists details to the surgeon/oncologist and explain there are potential side effects you’d like them to discuss, and a list of any medications you’re on for MG if any. But I’d also give your neurologist a heads up incase they have any knowledge of this situation to give you up front / to make sure they are contacted!
Hope it all goes ok for you x
