Experimental Confirmation of a Distinctive Diffraction Pattern in Hair From Women With Breast Cancer

The study confirmed that a distinctive diffraction pattern in hair could be associated with breast cancer, as initially reported by James et al. Two double-blind experiments were conducted using hair samples from the same patients. The first experiment, which followed James et al.'s protocol, consistently showed distinctive changes in the diffraction patterns of hair from breast cancer patients. However, the second experiment, which used a different protocol, did not show these changes, highlighting the importance of strict adherence to the original protocol. The study emphasized the need for careful sample alignment and mounting to detect the changes reliably.
