Delaying post-surgical radiation increases risk of breast cancer recurrence in older women

day. "There isn't a large difference between 43 days instead of 41," commented Punglia. "The day-to-day risk increase is very small."

The rise in breast-conserving surgery in the past two decades has fueled greater demand for radiotherapy, and might be one cause of longer waiting times. The study revealed more delays in areas such as the Northeast, where the procedure is more common, and fewer delays in the southern states, where breast-conserving surgery is less common.

Waiting times were also longer in cases involving African-American and low-income women, but the study did not pinpoint the exact source of the delay. "It could be factors such as access to care, the patients' ability to navigate the healthcare system, or physician referrals," said Punglia.

Although the study focused on older women, the findings have implications for younger women.

"It's possible that the increased risk we identified in older women could be magnified in younger women, whose tumors are biologically different and tend to be more aggressive," said Punglia, who is also an assistant professor of radiation oncology at Harvard Medical School.
