Hi @MelVE - sorry to see you here ... lots of terrific advice given already - definitely stay away from Dr Google as much of it is also out of date too, as advances in treatment have been enormous in recent years - including using immunotherapy.
Yep, try not to get ahead of yourself - it will only muck with your brain xx Try & stay 'in the present' (dealing with today's issues) and tomorrow's will sort themselves out ;)
Wishing you all the best with your surgeon's appt today - then keep as busy as you can between now & any surgery/treatment xx
I think being diabetic really only comes into play if you need chemo - and even then, it may depend on which one? My husband was diabetic & we just had to make sure he didn't have cereal/toast on the days of his infusion (just 2 boiled eggs) so his blood sugar wasn't too high, as the tablets (and some of the infusion) elevates the blood sugars anyway, so didn't want a 'double hit'.
Check out this post for a lot of 'general' info on the forum ..... and if you find yourself feeling a tad overwhelmed, give our Helpline a call on 1800 500 258 for a private chat xx. There are some 'tick sheets' to help you 'self assess' your own stress levels too, down the bottom of the post xx
