Deposit detection: Spectroscopy against breast cancer
Date: Jan 7, 2013
Author: David Bradley
Minute deposits of calcium in breast tissue act as a marker for breast cancer. Diffuse reflectance spectroscopy has now been used to show how deposits in benign conditions can be distinguished from those present in the early stages of the disease.
