PET Scans Predict Breast Cancer Spread

Positron emission tomography (PET) scans can help doctors ascertain whether breast cancer has spread to the axillary lymph nodes in the armpit area, California researchers have determined. A study out of Cedars-Sinai Medical Center in Los Angeles included 51 women with invasive breast cancer, whose average age was 54. Before the women had surgery or chemotherapy for their cancer, they all had PET scans after they'd been injected with a material similar to glucose (fludeoxyglucose F 18, or FDG), along with a chemical tracer. Cancer cells use more FDG than normal cells. The researchers analyzed the PET scans to determine each patient's standardized uptake value -- how much of the FDG was absorbed compared to how much of it was injected. --Click the title of this post to read the full article from its source--
