After a single session of transcranial electrical stimulation (tES), researchers noted a significant reduction in blood flow to brain tumors. However, there were no alterations in blood flow or activity in the rest of the brain. The technique may be helpful in the treatment of brain cancers such as glioblastoma.
Researchers have shown that infrared and Raman spectroscopy – coupled with statistical analysis – can be used to tell the difference between normal brain tissue and the different tumor types that may arise in this tissue, based on its individual biochemical-cell ‘fingerprint’.
A new probe developed uses an innovative fluorescence-reading technology to help brain surgeons distinguish cancerous tissue from normal tissue. The probe tool, now already in use at the Cancer Center for brain surgery, may one day be used for surgeries for a variety of cancers.
