Searching for ... what ,exactly?

I am having an MRI of my pancreas done this morning.  I am nervous.

I went to the Doc a few weeks ago because my poop was white.  It was after I attended a BBQ (most excellent flavors) that included very high fat meats.  I figured (and the Internet confirmed) that I should tell the Doc about it.  White is not a normal color for poop.  Blood tests, urine tests, ultra sound tests - all reveal that there is nothing wrong with me.  No stones, no blockages.  So, today is the MRI.  To look for cancer basically.  I think that this is all that is left to look at.

I do not like the idea of being in a certain position for an hour...and not moving.  I do not like the idea that - if there is any metal in your body, you could get hurt by the magnetic pull of it.  I don't know if I have metal in my body.  Nobody put any there - but, who knows what may have happened?  Something in my eye?  Maybe aliens put something inside me, I am always playing in the dirt and doing dirty things.  My Doc said I should take 2 tranquilizers.  That is good.  I don't want to feel freaked out.  Like I already do - and my anxiety grows as the minutes pass.

Well, I leave in 3 minutes.  Going to take my pills.  Wish me luck.

As much as I do not like the idea of this test - it is an excellent thing, isn't it?  To be able to see the insides so clearly.  Amazing really.
