Dear Donnarose- finding ways to laugh is a good thing! What you all are dealing with is not so good and the stress is normal. Altho I don't know "percentages", I do remember John signing forms before wvery surgical procedure that stated there was a percentage of danger involved- it's just something we have to live with. Hee's a story you might relate to- a dear friend of mine, who is a very smart nurse with 30 yrs.experience is now caregiver to her husband with liver cancer. During a recent Dr. appt., the surgeon told them that he was going to remove 1\4th of Ray's liver- my friend, dazed, asked "and what percent is that?". She has shared that with all of us, laughing about it while pointing out that dealing with cancer will put your brain and emotions into a tailspin. STay strong. Amy in the Ozarks
