Rehabilitation assessment phases in the PSM are
preoperative, early postoperative, and ongoing surveillance.
Entry into the PSM model occurs around the preoperative
and postoperative period because surgery is the
first intervention for the majority of breast cancer patients.
The PSM, therefore, will be most relevant for newly diagnosed
women with stage 0-III breast cancer before and after
breast-conserving surgery or mastectomy, with or
without reconstruction. Women with stage IV breast cancer
have significant aggregate effects of treatment that
may also benefit from rehabilitation intervention.84
Although the PSM does not address these women specifically,
it is anticipated that the ongoing surveillance phase
of the model will enhance access to rehabilitation care and
exercise for women with metastatic breast cancer
