Need Advice

Need advice from you wise woman or anyone reading this post with knowledge and experience. I found out this week I have a positive mutation for ATM. It's very rare and only 1% of the population are carriers. It's considered a moderate risk for BC however in general it's about 50%. risk for recurrence. I received very little information from my genetic counselor and will be meeting with the Genetic Oncologist next week. I have lots of questions to ask her.

In the meantime my BS office called yesterday to schedule an MRI. My PA asked if it was too soon to discuss surgery. I said I would meet with the BS next week after my appointment with the Genetic Oncologist. I suspect the BS is going to recommend a BMX or increased surveillance. The thing is with this mutation, radiation may be a problem though everything I read said these findings are not conclusive. I've already had a lumpectomy and radiation on my left breast. So just add that to my stress level as well as the implications for my daughter

So these are my questions.

1. Does the location of the mutation on the gene determine the percentage of your risk factor?

2. How would I get a second opinion re surgery options from another BS?

3. Should I also schedule an appointment with my MO?

As you can relate, I'm a nervous wreck. I'm anxious and oh by the way I am claustrophobic although with an anti anxiety medicine I can tolerate the breast MRI because it's face down. I'm not sleeping. I have to make peace with the decision to move forward with the BMX. I know reconstruction is not an option for me. I don't want implants and the radiated breast would be a problem,

Any words of wisdom would be helpful. I know that I'm fortunate that at this moment my cancer has been contained and I offer a prayer of gratitude for that and all the positive things in my life. I think once I have a plan things will settle down and I won't be as overwhelmed.
