Biotin Supplements Warned to Interfere with Cancer Treatment, Affecting Lab Results
Doctors at The Ohio State University Comprehensive Cancer Center have raised concerns about the use of biotin supplements by cancer patients. Biotin, commonly taken to improve hair and nail health, is found to potentially interfere with lab tests critical for monitoring cancer treatment. Dr. Brittany Dulmage, an oncodermatologist, highlights that while biotin is essential for keratin production, its supplementation is often unnecessary due to its abundance in everyday foods. The supplements can lead to inaccurate lab results, affecting the monitoring of cancers such as prostate, thyroid, ovarian, and breast cancer. This interference can result in false readings of hormone levels, potentially delaying or altering treatment plans. The study, published in JCO Oncology Practice, urges oncologists to discuss these risks with patients.
