thank you for the info on nurse practitioner. I will be glad to see Monday come and get the pet scan then Thursday I have the mri, the 3rd I am back to hemo doctor to get results . One thing I have learned in to reading this post and other people's views are it doesn't make it any better to get nervous about something you know nothing about until the time comes and I know the results and the options I have I am going to enjoy my life and try to make the negative thoughts positive ones and thank god I am still here. big hugs to all for being so caring.
