Breast Cancer Stem Cells Seem to Survive Radiation Therapy

Breast cancer stem cells, a type of cell that scientists have recently discovered is difficult to kill, may be especially resistant to radiation therapy, a new study suggests. In fact, the radiation can even increase the growth of these stubborn stem cells, report researchers from the University of California, Los Angeles, David Geffen School of Medicine. "This population of stem cells is more radiation-resistant than are non-stem cells," said Dr. Frank Pajonk, an assistant adjunct professor of radiation oncology at UCLA and corresponding author on the study. "We are the first to report this." Radiation treatment involves exposure to high-energy rays or particles that destroy cancerous cells. It is often recommended after surgery for breast cancer, according to the American Cancer Society. --Click the title of this post to read the full article from its source--
