Member spotlight: Kristina Mirabeau-Beale, MD, MPH

By Lauren Byrd, FMA VP of Communications and Strategic Partnership 

For FMA member Kristina Mirabeau-Beale, MD, MPH, a career in radiation oncology began with a simple but powerful realization: Every patient’s story matters.

“When I started at Harvard Medical School, I was sure I was going to be an OB/GYN,” said Dr. Mirabeau-Beale, who serves as co-chair of the U.S. Breast Cancer Research Group for GenesisCare, a regional cancer center in Fort Myers. “But through early research and patient interviews at Dana-Farber Cancer Institute, I learned the power of hearing a patient’s story in full. Those experiences showed me how deeply personal the cancer journey is.”

That experience, combined with her background in anthropology and women’s studies, sparked her passion for oncology. Today, she treats patients experiencing breast cancer at every stage.

“Radiation oncology is a very visual, collaborative field. I love that it blends technology, physics, and patient care.” 

A rewarding role

Witnessing hope and healing at every stage is one of the most meaningful parts of Dr. Mirabeau-Beale’s work in caring for breast cancer patients.

“Many of our early-stage breast cancer patients have curative disease,” she explained. “It’s incredibly gratifying to reassure a patient who’s anxious about their prognosis that they’re going to do great.”

She also finds deep purpose in supporting patients with advanced disease. 

“Radiation can bring real relief from pain and symptoms,” she said. “And when treatment is no longer fruitful, I value being able to have honest, compassionate conversations about end-of-life care — helping patients and families make decisions that align with their goals.”

Connecting with compassion

Dr. Mirabeau-Beale’s care extends well beyond the technical aspects of radiation therapy. She focuses on emotional support and wellness for her patients and their families.

“I never do my notes while a patient is talking,” she said. “I make eye contact, I listen, I give hugs when they’re wanted. That presence builds trust and hope.”

She also discusses sleep, nutrition, and lifestyle habits with patients to support their recovery.

Advocacy and leadership

By participating in the FMA’s Karl M. Altenburger, MD Physician Leadership Academy, Dr. Mirabeau-Beale has found new ways to make an impact beyond the clinic.

“The Leadership Academy opened my eyes to how important advocacy is,” she said. “Across specialties, we share common challenges, and physicians have an essential role to play in shaping health policy. It’s been a call to action for me.”

The program has also brought personal rewards. “I’ve made real friendships, found new mentors, and connected with colleagues who’ve become collaborators,” Dr. Mirabeau-Beale said. “It’s been incredibly fulfilling.”

A message for Breast Cancer Awareness Month

“Our specialty is data-driven and collaborative,” she said. “We design care plans that optimize outcomes while protecting quality of life. Radiation oncology isn’t just about X-rays. It’s about compassion, collaboration, and helping patients live their best lives.”
