A system and method for using near-infrared or short-wave infrared (SWIR) light sources for early detection and monitoring of breast cancer, as well as other kinds of cancers may detect decreases in lipid content and increases in collagen content, possibly with a shift in the collagen peak wavelengths and changes in spectral features associated with hemoglobin and water content as well. Wavelength ranges between 1000-1400 nm and 1600-1800 nm may permit relatively high penetration depths because they fall within local minima of water absorption, scattering loss decreases with increasing wavelength, and they have characteristic signatures corresponding to overtone and combination bands from chemical bonds of interest, such as hydrocarbons. Broadband light sources and detectors permit spectroscopy in transmission, reflection, and/or diffuse optical tomography. High signal-to-noise ratio may be achieved using a fiber-based super-continuum light source. Risk of pain or skin damage may be mitigated using surface cooling and focused infrared light.

Near-infrared super-continuum lasers for early detection of breast and other cancers

The combination of contrast enhanced magnetic resonance imaging (MRI) and MR-guided subcutaneous core biopsy can be used as a robust approach for the diagnosis and treatment of breast cancer. MRI provides the means to accurately position and monitor interventional procedures such as biopsy, removal of tissue or other transcanular procedures. MRI may also be used in this invention to position and monitor the progress of breast conserving therapies (BCT), such as laser photo-ablation, cryoablation and localized hyperthermia. The general practice of this invention is to provide a remotely controlled apparatus for MR-guided interventional procedures in the breast. The apparatus allows the practice of a method that provides flexibility in conditioning the breast, i.e. orientation and degree of compression, and in setting the trajectory of the intervention. To that end, a robust conditioning/positioning device, fitted with the appropriate degrees of freedom, enhances the efficacy and efficiency of breast interventions by providing the flexibility in planning and executing an appropriate procedure strategy that better suits interventional procedures, either those in current use or yet to be developed. The novelty and potential commercial success of the device originates from its high maneuverability to set and perform the procedure strategy and its adaptability to accommodate an array of interventional probes. Remote control of this device can allow planning the operation and performing the relevant tasks in a short period, for example, within the contrast window provided by a single injection of a contrast agent, and this feature can be operator-independent.
