The shorter therapy schedule, which is more intense, is also cheaper, and most women preferred it when given the option.

While two-thirds of women in Canada and Britain received the shorter version of the radiation therapy, The New York Times predicts that the shorter courses won't catch on among American doctors, as it will take time to "change ingrained medical practices, especially when a procedure has been used for decades." There's also no medical benefit, which means there's not much of an incentive for doctors to prescribe the shorter course — the benefits lie only in patients' time and health insurers' wallets.
