Lymphadema and weight lifting?

Breast cancer survivors who lift weights are less likely than their non-weightlifting peers to experience worsening symptoms of lymphedema, the arm- and hand-swelling condition that plagues many women following surgery for their disease, according to new University of Pennsylvania School of Medicine research published in the New England Journal of Medicine. The findings challenge the advice commonly given to lymphedema sufferers, who may worry that weight training or even carrying children or bags of groceries will exacerbate their symptoms.

I haven't called my physical therapist yet to see if this changes her recommendations. She's a certified lymphadema specialist and her recommendations have always included not doing heavy lifting with the effected side, not vaccumming, or mowing the lawn. Now that I think about it, I'm not entirely sure I should call her....what do you think?
