I saw an article the other day where some oncologists are also recommending against post-lumpectomy radiation for women over 60 who had early stage cancers excised.

There is a lot of reexamining possible 'over-treatment' of early-stage cancers now that more are being detected. At least among older women whose breast cancers are often less aggressive and slower-growing than the same cancer in a younger woman. [And then, on a more cynical note, insurance companies save money. There's a lot of policy pressure to spend less on elder health in general. ]
