In fact, many studies show a lower risk of recurrence and death among women who eat more soy. JAMA Network* A 2023 systematic review and meta-analysis found that soy isoflavones were associated with about a 26% lower risk of recurrence overall, with the strongest benefit in postmenopausal and estrogen-receptor–positive survivors. The greatest risk reduction showed up around 60 mg of isoflavones per day—roughly what you’d get from 2–3 servings of traditional soy foods. PMC* Some studies suggest that women with ER-positive cancers who are taking tamoxifen and also eating more soy actually do better—they have lower recurrence risk compared to tamoxifen users who eat very little soy. PMC* Major organizations like the American Cancer Society and American Institute for Cancer Research now state that soy foods are safe for breast cancer survivors and may even help reduce recurrence risk, including for women with ER-positive disease. They do, however, draw a line between whole foods and high-dose supplements, because we have far less safety data on concentrated pills and powders. American Cancer Society This is a public episode.
