Could estrogen protect you from breast cancer?
Your DNA might hold the answer.
Discover how the KRAS-variant can help determine if hormone replacement therapy (HRT) may reduce your breast cancer risk.
Women with an inherited biomarker called the KRAS-variant may be at higher risk of developing breast cancer when estrogen levels decrease—such as during menopause, after ovary removal, or when stopping menopausal hormone therapy (MHT), formerly hormone replacement therapy (HRT). For some women, estrogen may play a protective role.1
Take action:
- Find out if your DNA shows that you may benefit from being on estrogen for protection.
- Use your genetics to create a breast cancer prevention plan that’s truly personal.
- Take control of your health with information that empowers personal choice.
A simple genetic test can tell you if you carry the KRAS-variant.
“For me, it’s good to know. Because the best time to fight cancer is before it’s already spread, right when it starts.”

About MiraKind
MiraKind is a nonprofit organization founded by Joanne Weidhaas, M.D., Ph.D., following her co-discovery of the KRAS-variant, a novel genetic biomarker with profound implications for cancer risk, prevention, and treatment. Through ongoing research, MiraKind has identified hundreds more such variants and works to support patients and doctors in making safer, more informed treatment decisions that help avoid side effects and improve outcomes.
Why Donate?
Personal genetics is the future of cancer care. You can help us get there faster.
MiraKind is pioneering research into inherited genetic variants—like the KRAS-variant and hundreds more—that help predict cancer risk, guide treatment choices, and open the door to more effective prevention.
Your donation helps:
- Advance research that shows how our DNA shapes cancer risk and treatment outcomes
- Expand access to genetic testing for the people who need it most
- Equip patients and doctors with trusted, easy-to-understand information for better decision-making
This work isn’t just about breast cancer. And it’s not just for women. It’s about making medicine more personal—for everyone.
