Long-term exposure to low-dose radiation is linked to an increased risk of cancer, according to a study led by the University of California, Irvine. In the U.S., radiation exposure for the average person doubled between 1985 and 2006, mainly from medical imaging procedures such as CT scans, highlighting the need for its judicious use.
Both radiation and temozolomide, a generic chemotherapy treatment in pill form, have meaningful single-modality anti-tumor activity against slow-growing, low-grade gliomas.
