@callalloo I posted this study elsewhere though the focus was on the fact that radiation for those >65 made no difference in terms of metastasis or overall survival. The focus here seems to be more on the increased risk of local recurrence, without radiation. In either case I posted again that noone should make treatment decisions based on this study, without consulting a doctor.

Here is an excerpt: The investigators concluded, “Omission of radiotherapy was associated with an increased incidence of local recurrence but had no detrimental effect on distant recurrence as the first event or overall survival among [patients] 65 years of age or older with low-risk, hormone receptor–positive early breast cancer.”
