Study Finds No Link Between Age-Related Biomarker and Breast Cancer Spread

This study found that methylmalonic acid (MMA), a substance that accumulates with age, is not associated with metastasis of breast cancer in humans. This is important as a follow-up to an animal study suggesting that accumulation of MMA leads to progression of breast cancer, with this study finding no such relationship in humans. Co-author Ana P. Gomes was funded by a Lung Association Innovation Award.
