Hi Lisa,
My second surgery (2 years ago this month) was also broken off because the recurrence was stuck on the IVC.
I’m still alive and kicking and doing very well– after work today I’m going to do my usual 6-mile run. So, it’s a real bummer that they couldn’t operate on us because of the location, but I don’t think that having the tumor there necessarily is dangerous.
If you’re really concerned about it, you should ask your doctor– but I don’t think it helps us to worry a lot about things that might maybe happen in the future, if there’s not a thing we can do about it.
Hope this helps! By the way, I love your blog!
