When will it stop..

I have been asking myself this question since last week.  Last week, my Mom had to go in for her annual mammogram.  The next day, she received a phone call that they wanted her to go in and have an ultrasound done.  Apparently there was something on the mammogram.  So she went in yesterday and had it done.  According to the tech, there didn't appear to be anything there.  But she won't know for sure until her doctor receives the results.  Now on to my Dad.. he has an aneurysm and has had it for a few years. It was quite small.  The doctors have told him that they can't do anything until it reaches a 5.  So for the past couple years, he has been going in to have it looked at every 3 months.  When they first found it, it was at a 3.. and after about a year or so it went up to a 4 where it has remained.  Well, now it has jumped up to a 6.  So today, he had to go in for a CT scan just to be sure that it is actually a 6.  Regardless if it is or not, he will have to have surgery to put a stint in his aorta.  And once again, we won't know anything until next week. This is just frightening to me.. I think that it worries me more just because my Dad is older (he's in his 60's).  I know that surgery is risky anyways, but to add age on top of it and high blood pressure.. no good.  All I can do at this point is pray and just stay positive.
