Tumors causing Diabetes/ Causing Insulin Resistance?

[ThatGirl]

I have Multiple Endocrine Neoplasia, Type 1; from tumors in my Pancreas, I have Diabetes, Type 2. I just posted a question about why my insulin resistance has increased:

I'd like to rephrase: Could it be that the Pancreatic tumors are making me more insulin resistant? Could they be affecting me so that although I have lost weight and have gone down several sizes, I am becoming more insulin resistant anyway? Could there be other tumors growing somewhere else in my body that do this? And could someone explain why these tumors in the pancreas cause diabetes?

I'm not going to freak out; I will take everything you say and run it by my doctor; and bless you from the soles of your feet to the crown of your head... ;-)

(It's just that my doc is a little dim- he can't figure this out on his own [Jeez, I wish I had studied medicine! I tell you, a Literature Major is no help! ;-) ] )
