Fewer, stronger doses of radiation are just as effective as more frequent, weaker treatments for women with breast cancer, researchers found.
A 10-year trial sponsored by Cancer Research UK found that 13 bigger bursts of radiotherapy were as effective in preventing breast cancer recurrence as 25 smaller doses, the researchers wrote in the journal Lancet Oncology. Women who had the stronger doses also had no greater risk of side effects, the scientists said.

Fewer treatments would reduce the inconvenience of radiotherapy and probably would be more cost-effective, they said.
Among 1 410 women who participated in the study, those given 25 doses of radiation over five weeks had a breast-cancer recurrence rate of 12.1 percent, while women given 13 doses in larger amounts over the same span had a recurrence average of 12.2 percent, according to a report in the London Telegraph. – (HealthDayNews)
