Once I learned of my stage, etc., yes, I worried from time to time (haven't had any treatment yet, surgery Sept. 16).
I had a pain just below my ribs on my right side: oh my, has it spread to my liver? Had a pain in my back just below the last rib: oh my, has it gone into my rib?

It is hard not to do but I have found that just telling myself that is "stinkin' thinkin'" and use my belief system to give the troubling thoughts away.
