What makes ascending thoracic aortic aneurysms increase in size?

I am a 68 year old woman, who considers myself in relatively good shape and health until I was diagnosed with breast cancer 14 months ago. I had a lumpectomy and radiation and now I am on medication which increases cholesterol, causes joint pain, and osteoporosis. In June 2024, I had a CT Scan with contrast due to the cancer and that was fine but I found out I had a 4.1 ascending thoracic aortic aneurysm, which caused me to freak out. My cardiologist had no concern, so I saw a Thoracic Surgeon who said since I’m short, surgery would be needed if it reached 4.5. Typically, they recheck in a year but since I was nervous I just had a CT Scan on 1/17/2025 w/o contrast. I just received the results today, is it really beneficial so see results populating in your portal before you speak to the doctor, not…. anyway… it is now 4.3 so it grew in 7 months. I retired to relieve stress, do Pilates, use my elliptical, increased my BP to 100 mg, I occasionally have a glass of wine or Cosmo at dinner once a week. I don’t have a good feeling about this and I’m trying to be positive but I’m really struggling today.

Are there any statics on how often aneurysms increase in size compared to no change? Are there any statistics on how many people who have surgery survive the surgery but die from complications, or life span after surgery.

I always look for a solution and not one to give up but not being able to fix this is making me crazy.

Also, it seems doctors have a cavalier approach because there really isn’t anything they can do, basically the odds are 50/50…maybe.

Any inspirational hope from anyone?
