New smartphone attachment can detect cancer

Researchers at Washington State University have developed a portable sensor that uses a smartphone's camera to detect a biological indicator for several types of cancers with 99% accuracy, yielding laboratory quality results.
The sensor, a light spectrometer, can process up to eight blood or tissue samples at the same time (or one sample in eight wells) and can detect the human protein  interleukin-6 (IL-6). That protein is a known biological marker for lung, prostate, liver, breast and ep
