gentler, more accurate mammogram?
breast imaging may outperform mammography.
mammography finds breast lesions at a median size of 11 millimeters,
roughly the size of a garbanzo bean.
John M. Boone, professor of radiology and biomedical engineering,
has designed a machine that may perform better.
With fellow radiology professors Anthony Seibert and Karen Lindfors
at UC Davis and Tom Nelson at UC San Diego, Boone has built a prototype
breast CT that has the potential to detect lesions in the 3- to
5-millimeter range, about the size of a pea.
That would allow doctors to find and treat tumors 12 to 18 months
earlier — the time it takes a typical 3- or 5-millimeter tumor
to grow to 11 millimeters.
Boone says the 15-year survival rate for breast cancer, now about
86 percent, could increase to 97 percent if breast tumors were routinely
detected in the 3- to 5-millimeter range.
