Hi Kerin,
no need to apologize about the length of your post. You have a lot going on and it's good to get your thoughts out.
I would ask your medical advisors if they feel a Breast MRI might be useful in addition to a mammogram. Some insurance companies will pay for that if you are considered at high risk and with your TNBC diagnosis, gene mutation and family history I believe you would qualify. The gold standard for high risk women seems to be alternating Breast MRIs and mammograms every 6 months. And there are variations on the theme with some centers ordering Breast MRIs yearly or mammograms yearly but from what I have seen the 6 months alternating program is often used. Also, if you have dense breasts (no response required..just want you to be aware that MRIs are preferred in that case..but mammograms still used) Breast MRIs seem to be preferred even with the downside of false positives.
I have heard good things about the Block Center.
The anxiety you are experiencing is a natural, normal feeling in my view. July 11th will come and go and be , hopefully, uneventful and then you can relax a bit.
warmly,
Steve
