Sorry to hear about your dad, It can be so frustrating at times. What ever you do don't blame yourself for missing a sign,or a problem. You may be a nurse,but when it comes to family, objectivity comes into play.Right now your mom needs you more then ever,just to answer questions and to explain. My prayers are with you,and if you ever want to talk send a message, Also thank you for replying to my message, I'm the one who is questioning the CAT scan, and got the awful news. Right now we are waiting for the results of the biospy. Our surgeon comment on the procedure," I have deep concerns" That leaves you alittle stressed.She is calling us on Monday...I hope it is not another call of doom...I would like to meet a hopeful doctor,hopefully I will find one. Thanks for the tip on writing things down....plc
