BRCA1 Genetic Testing Empowers Cancer Prevention
A family shares their experience with BRCA1 testing to encourage proactive health decisions after a cancer diagnosis.
Updated on Oct. 28, 2026 in Cancer
After being diagnosed with triple negative invasive ductal carcinoma in 2020 at age 34, Sarah Sanders tested positive for the BRCA1 gene mutation. She reached five years of being cancer-free in 2026 and prompted her family to undergo genetic screening.
Why it matters
Sarah Sanders notified her cousins of the 50% chance they inherited the BRCA1 mutation to help them manage their own long-term health risks. This initiative underscores the importance of hereditary screening for breast cancer, which is the leading cause of cancer deaths in U.S. women aged 20 to 49.
Sarah Sanders received her cancer diagnosis at age 34, while her cousin Mable Sanders currently faces decisions at age 27. Current research tracks an annual 1.4% increase in breast cancer diagnoses across the population.
The players
Sarah Sanders
A breast cancer survivor who was diagnosed with triple negative invasive ductal carcinoma at age 34.
Mable Sanders
A 27-year-old cousin of Sarah who tested positive for the BRCA1 mutation and is considering a prophylactic mastectomy.
Norely Sanders
A cousin of Sarah who tested positive for the BRCA1 mutation after undergoing genetic testing.
The details
Following her own recovery, Sarah Sanders encouraged her cousins Mable and Norely in Denver to seek testing for the BRCA1 mutation. Doctors now offer pre-implantation genetic testing during IVF to identify embryos that do not carry the specific mutation.

Health Landscape
The use of genetic screening reflects broader advancements in hereditary risk assessment, mirroring the protections established by the Genetic Information Nondiscrimination Act. These tools allow individuals to move from reactive treatment to proactive preventative care.
Individuals with a family history of breast cancer should consult with their healthcare provider about the potential benefits of genetic counseling and testing. Understanding your hereditary risk profile can lead to earlier interventions and informed choices regarding prophylactic treatments.
The takeaway
Proactive genetic testing provides individuals with the necessary information to make informed decisions about preventative care and long-term health management. Sharing family health data remains a vital step in identifying risks and improving outcomes for relatives.
