Miami Researchers Get $2.7M to Fight Cancer Stress Aging

Breast cancer survivors may soon have a powerful new tool to protect their long-term health, thanks to a groundbreaking study launching at the University of Miami.

Researchers at Sylvester Comprehensive Cancer Center just received $2.7 million to study whether managing stress can actually slow the aging process that cancer and chemotherapy speed up in survivors. The SMART-PATHS study will enroll 192 postmenopausal breast cancer survivors over the next three years.

The team is testing a 10-week virtual program that combines cognitive behavioral therapy with relaxation techniques like breathing exercises and progressive muscle relaxation. Participants join live group sessions from home and access expert videos and resources on demand.

Dr. Michael Antoni, who leads the study, has spent nearly three decades studying how stress affects people with chronic illness. His earlier research found something remarkable: survivors who completed the stress management program showed actual biological changes, including improved immune cell function and slower cellular aging.

The connection between stress and aging runs deeper than most people realize. Cancer treatment can speed up aging at the cellular level, affecting immune function, hormones and even brain health. Many survivors continue feeling stressed long after treatment ends, worrying about recurrence or lasting health changes.

That ongoing stress may keep driving the aging process forward. The new study will track participants for up to two years, measuring stress hormones through saliva samples, inflammatory markers in blood, and daily patterns using wearable fitness trackers.

Dr. Carmen Calfa, who collaborates on the project, explains that Sylvester wants to do more than just cure cancer. The center is equally committed to reducing the negative impacts treatment leaves behind.

The Ripple Effect

Postmenopausal women make up the largest group of cancer survivors in the United States. They often face persistent stress symptoms and show signs of aging earlier than peers who never had cancer.

If this telehealth program works, it could reach thousands of survivors who struggle to attend in-person therapy sessions. The pilot version already showed strong participation, with survivors attending live sessions regularly and using on-demand resources frequently.

Dr. Frank Penedo, who directs the Sylvester Survivorship and Supportive Care Institute, notes this period right after active treatment ends is crucial. That's when stress management could make the biggest difference in preventing accelerated aging.

The study represents a shift in how medicine thinks about cancer care. Surviving cancer is just the beginning. Living well afterward matters just as much.
