ATM Gene Mutation, Stage 1 Breast Cancer & Why Genetic Testing Matters with Krista Brown

If you've been diagnosed with an ATM gene mutation, have a family history of breast cancer, or are wondering whether genetic testing could change your future, this conversation is for you.

In this episode of BRCA & Beyond, I sit down with Krista Brown, MS, RN, CFNC, an oncology nurse navigator, breast cancer survivor, and hereditary cancer advocate. Krista shares her powerful journey after learning she carries an ATM gene mutation, how enhanced screening detected her Stage 1A breast cancer just weeks before her planned preventive mastectomy, and why she believes earlier access to genetic testing could have prevented her diagnosis.

Krista is an Oncology Nurse Navigator in Phoenix, Arizona, with more than 14 years of nursing experience. As a breast cancer survivor and carrier of an ATM gene mutation, she's passionate about hereditary cancer education, genetic testing awareness, evidence-based prevention, and helping individuals and families make informed healthcare decisions.

Together, we discuss hereditary cancer, inherited cancer risk, genetic counseling, breast cancer screening, prevention, advocacy, survivorship, and the emotional realities of living with a hereditary cancer gene mutation. We also talk about the gaps that still exist in patient education, why genetic testing matters, and how sharing our stories can create meaningful change for future families.

Whether you're living with an ATM, BRCA1, BRCA2, PALB2, CHEK2, TP53, PTEN, CDH1, STK11, Lynch syndrome (MLH1, MSH2, MSH6, PMS2, EPCAM), RAD51C, RAD51D, BARD1, NBN, BRIP1, or another hereditary cancer gene mutation, or you're supporting someone who is, this episode offers education, hope, and honest conversation.
