Generally, a medical diagnosis of disease, or impairment, is necessary prior to the implementation of any medical intervention or treatment. In the case of secondary lymphedema following primary medical treatment (surgery, chemotherapy and/or radiation) the overall incidence of lymphedema has been estimated to be 20-25%. As such, if one were to provide compression sleeves to all patients following treatment, 75-80% of these patients may be inappropriately treated for a non-diagnosed condition.
In the absence of a diagnosis, patients are less likely to be compliant with a medical intervention over a long period, such as the 36 months of highest risk following their primary treatment. Compliance with a short interval of intervention, as demonstrated in a study conducted by the NIH (Cancer, June 2008)  is more likely to be successful.
Improper fitting or wear of compression sleeves provided prophylactically to all patients could actually promote constriction of the arm and subsequent swelling and other vascular complications.
Fitting such sleeves to all patients could subject them to unnecessary cosmetic and comfort issues.
Lastly, the cost of these sleeves (2 per year) could be significant to the patients or health insurance provider over time.
