VIDEO: Finding cancer cells before they become tumors
Researchers have developed a way to detect cancerous melanoma cells in the body before they grow into a tumor. The process uses a new device that reads blood cells through photoacoustics. The device shoots laser light into a blood sample, which is absorbed by melanin inside the cancer cells. As the cancer cells expand, they become easily visible to lab technicians, making it possible to provide an early diagnosis.
