Evidence of link between cancer, light therapy inconclusive but warrants consideration

Two new studies raise enough questions about a possible link between childhood cancer and light therapy for newborn jaundice that clinicians should exercise caution in prescribing it for infants whose jaundice will likely resolve on its own. The suggestion of a link, however, should not deter use of the treatment, also known as phototherapy, in babies who otherwise would be at risk of brain damage or hearing loss.
