Hi Hope, welcome to the Breast Cancer group. I'm tagging a few fellow members who have also posted about genetic mutations helping them in their treatment choices, such as @starko @coffeefreak and @dianamiracle. You may also find these related discussions helpful:

@hopediekman, how might the results of your genetic testing influence your choice between lumpectomy and mastectomy?

Hi Colleen, if this is a high risk familial mutation for breast cancer I probably would chose mastectomy over lumpectomy but upon further research of this mutation I have found that there isn’t much evidence yet of it being so. One genetic testing institution has called it likely pathogenic (the one that did my test) and another has called it VUS (variant of unknown certainty). I did literature searches on the variant and didn’t find any clinical evidence either on it. As of right now I am going to opt for lumpectomy should I get that option after chemotherapy is completed.

I also have the RAD50 mutation and changed my surgery from lumpectomy to B mastectomy.

Welcome @kmuir. I'm sure @hopediekman will appreciate connecting with someone else who has the RAD50 mutation.

Kmuir, have you had surgery already?

I had surgery 3 weeks ago. Tomorrow I see oncologist to find out what’s next. My children, siblings, and mother have also completed genetic testing with several of them also being positive for RAD50. Mother and maternal aunt both had breast CA.
