Patients will be recruited from the investigator's hospital's Cancer Assessment Center. Following cancer diagnosis, patients are seen by a surgeon 4 weeks prior to their scheduled operation. Following surgical assessment and confirmation of the decision to operate, patients who consent to consideration for research contact, and who meet all inclusion criteria except for frailty score, will be assessed by a trained clinician or clinical assistant using the Clinical Frailty Scale (CFS). Patients who score >4/9 on the CFS will then be randomized after providing written informed consent.
