Question: when does abdominal aortic aneurysm become dangerous?
Answer: These are the main factors that make a rupture more likely: The aneurysm is larger than 5.5 cm in diameter. The aneurysm has grown quickly (more than 0.5 cm in six months or more than 1 cm in one year). The aneurysm is causing symptoms such as pain in the back, stomach, or sides.
