The study's authors plan to continue tracking the participants' mortality and cancer recurrence rates and suggest more studies are needed to confirm their findings. Nevertheless, an editorial by Rachel Ballard-Barbash, MD, MPH, of the National Cancer Institute and Marian L. Neuhouser, PhD, of the Fred Hutchinson Cancer Research Center, published by JAMA alongside the study, notes that "clinicians can advise their patients with breast cancer that soyfoods are safe to eat and that these foods may offer some protective benefit for long-term health."

Dr. Ballard-Barbash and Dr. Neuhouser continue, "patients with breast cancer can be assured that enjoying a soy latte or indulging in pad thai with tofu causes no harm, and when consumed in plentiful amounts, may reduce risk of disease recurrence."
