Breast implant exchange (30 year old ones!) -- advice and recovery/pain?

I have 30 (yes 30) year old implants. They work fine honestly, breastfed two kids with them and they still look pretty decent. But I know they have a shelf life and I think I am past it. I talked to a surgeon who is highly regarded and I really like and he was like, yes at some point they are going to break, so I think I am going for it.

He makes it sound pretty cut and dry, recovery is 2 weeks, etc. and that it shouldn't be too too painful. I am nervous. Has anyone gone through this?

Did you get mammograms with them? i have been doing ultrasounds 2x a year to avoid the compression but might go ahead with the mammo pre- surgery. Not positive though.
