Avoid Multiple Breast Cancer Surgeries by Terahertz Imaging
Filed in archive Diagnostics on April 26, 2006
As introduced in the May issue of Radiology, there is a promising new technique that will ensure complete removal of tumors in breast cancer incisions. This new technique makes use of light waves in a newly explored region of electromagnetic spectrum called the terahertz region in examining excised breast tissue to determine if the removed tissue margins were clear of cancer. This new technology does the examination with good results and has the potential to eliminate the need for multiple surgeries.
"We found that terahertz light could reliably distinguish between normal breast tissue, tumor and even early-stage 'in situ' cancers in excised tissue samples," said Vincent P. Wallace, Ph.D., lead investigator at TeraView, who worked with Addenbrooke's Hospital in Cambridge, England, in conducting the study. "This technology could aid the surgeon in immediately identifying residual cancer after the main tumor has been removed, thus minimizing the need for additional surgical procedures."
At present, after breast cancer surgery, the excised tissue samples are sent for histopathologic examination that usually takes several days before completion. Therefore, the surgeons have no idea if the entire tumor has been removed until well after the surgical procedure has been completed. This usually leads to repeat surgeries to be scheduled. This setback will however be eliminated by terahertz imaging by allowing the surgeon to analyze tissue samples during the initial excision procedure.

How would you like to make a difference in breast cancer research? The Sister Study needs your help to determine if breast cancer is caused by something women come in contact with at work, at home, in their communities or in the personal products they use.
The Sister Study is looking for 50,000 women to help discover the environmental and genetic causes of the disease. Women ages 35 to 74 are eligible to join if their sister (living or deceased), related to them by blood, had breast cancer; they have never had breast cancer themselves; and they live in the United States or Puerto Rico.
ENROLL TODAY or simply help spread the word to women in your community! Either way, you can help find the causes of breast cancer!!
