thoracic aortic aneurysm

I'm reading all of your story and input with your experiences and I'm so glad that I found this group as my mom hapens to have accidently discovered has around 7cm thoracic aortic aneurysm that she does not even really know about besides what the first doctor she saw told her she has enlarged aorta after doing CT because of a lesion on left lung main bronch which hapened to be a tumor with still unclear histology.
My mom lives in Bulgaria and I live with my family in LA. She is going to heve on 07/02/25 new CT with contrast so the doctors will be able to get clear picture of her situation and than let me know about care plan for her.
I used to be an OR nurse some 20-25 years ago back home and understand that I'll need to go there and be with her in the time after surgery and in her first weeks of recovery.
For me reading all of your input is so helpful and vital. Thank you so much for any advise and information.
