I think if I had a 40mm AAA and money in the bank, I would be cashing in before cashing out......I asked and they said they don't plan intervention until it has swollen to 5cm diameter.
I'm at just over 4cm at the last screening. I think they move from yearly to 1/2-yearly to quarterly monitoring.
But it's of no value if you "pop" in the meantime for sure.
My thoughts are with you as it must be a scary time knowing family history etc.
