While social media and news outlets were reacting, or in some cases overreacting, to a new rodent-based medical study on the unlikely link between cell phone use and brain cancer last month, two studies and an accompanying commentary were quietly published in Pediatrics that raised similar concerns. Rather than cell phone use, the proposed potential cause of pediatric cancer in these newly published papers was phototherapy, a common treatment for newborn jaundice that I use regularly and have written about before. My previous post has a full review of jaundice in the newborn, how it can potentially cause permanent brain damage, and why phototherapy is a safe and effective treatment in most cases.
But is phototherapy truly safe? Can exposure to a narrow spectrum of blue light increase the risk of cancer in young children? And if so, what type or types of cancer? This is exactly what the study authors set out to investigate using the power of “Big Data.” Time will eventually tell us if the authors’ conclusions are justified or if they will end up only serving as excellent future examples of the Texas Sharpshooter Fallacy.
