@ali1974, there are several discussions about genetic testing for breast cancer here on Connect. For example:

- Genetic testing...does anyone have the CHEK2 gene mutation https://connect.mayoclinic.org/discussion/genetic-testing-does-anyone-have-the-chek2-gene-mutation/
- The math of invasive breast cancer risk for LCIS https://connect.mayoclinic.org/discussion/the-math-of-invasive-breast-cancer-risk-for-lcis/
- High Risk Mutation (ie. BRCA, ATM, RAD51D) https://connect.mayoclinic.org/discussion/high-risk-mutation-ie-brca-atm-rad51d/
- High risk, NOT from BRCA but from typia, such as ALH, ADH, LCIS https://connect.mayoclinic.org/discussion/high-risk-not-from-brca-but-from-typia-such-as-alh-adh-lcis/
– ATM Gene Mutation and Care https://connect.mayoclinic.org/discussion/atm-gene-mutation-and-care

In these discussions you'll meet others like @elsie37 @sandyjr @ladylawdawg @corinneberg @marykaym63 @patsydanley
