Intense radiation called effective

September 27, 2008|From Times Staff and Wire Reports

Intense radiation therapy for three weeks after surgery for early breast cancer keeps the disease at bay just as well as lower doses for five weeks, a study found.

More than 1,200 women were treated with either the accelerated three-week dose of radiation or the standard five-week therapy, then tracked for recurrences for up to 12 years.

The cancer returned to the same breast a decade after treatment in 6.2% of those treated for three weeks and 6.7% of those getting standard therapy, according to the study presented this week at the annual meeting of the American Society for Therapeutic Radiology and Oncology in Boston.
