Specialists at The Cleveland Clinic who provide radiotherapy for women with breast cancer are pioneering use of a shield designed to protect healthy breast tissue from scatter damage that might be caused by radiation that spills over from the treatment area to the healthy breast on the opposite side.
Development of the breast shield and the risk for contralateral breast cancer risk are outlined in a series of recent papers published by the Cleveland Clinic Research Group. The latest developments will be reviewed in a major paper appearing in the September 2001 issue of Radiotherapy and Oncology, the journal of the European Society for Therapeutic Radiology and Oncology. Roger M. Macklis, MD, Department of Radiation Oncology at The Cleveland Clinic, said researchers were prompted to develop the breast shield by the growing use of radiotherapy for women who receive breast-conserving treatment for breast cancer.
Macklis acknowledged that the risk for contralateral breast cancer has yet to be fully recognized in scientific literature. He said, however, that taking this precaution makes sense, given what is known about radiation exposure and breast cancer.
"As far back as studies of the victims of the atomic bomb in Hiroshima and before, doctors have known that breast cancer development is a risk of radiation exposure," Macklis said. "At the same time, radiation is a powerful therapy for the eradication of already existing cancer cells. In most radiation treatment centers, few, if any, precautions are taken to protect the healthy breast from scattered radiation. With the use of our new shield, however, doctors everywhere soon may be able to provide women with significant protection from this potential danger."
Macklis emphasized that radiation risks to healthy breast tissue in radiotherapy treatment appear to be insignificant for a majority of women. The review of data on contralateral ...
