The Duke University researchers have developed a tiny laser that could potentially be used to detect and treat skin cancer. By spotting the skin cancer at an early stage, the device can save many lives and a lot of people could benefit from it. The laser device is used to shoot double laser beams into the potentially malignant mole and its pigments are analyzed. If there are high concentrations of the black pigment in the mole, it could be an indicator of early-stage cancer.
Thousands of archived skin samples are going to be used by the researchers at Duke University to test the device. Previously, a method used since the 17th century and only with 85 percent reliability was utilized to detect skin cancer. The laser device will help in identifying the cancer and if there is cause for concern, the mole would have to be removed for detailed analysis.
