Behavior modification to reduce the risk of developing cancer is a major public health concern due to health care costs associated with individuals being treated for cancer. [12] Behavior change falls squarely within the interests of the field of psycho-oncology due to the psychological factors associated with implementing behavior change.
A retrospective study, on the other hand, looks backwards and examines exposures to suspected risk or protection factors in relation to an outcome that is established at the start of the study. Many valuable case–control studies, such as Lane and Claypon's 1926 investigation of risk factors for breast cancer, were retrospective investigations.

Cancer-related fatigue is a symptom of fatigue that is experienced by nearly all cancer patients. [1] Among patients receiving cancer treatment other than surgery, it is essentially universal.

The relative risk reduction was 57.7%. For patients at similar risk to those in this study (35.5% of patients had positive surgical margins following RRP), this leads to an absolute risk reduction of 20.5%. 4.9 patients must be treated for one to benefit (number needed to treat = 4.9).
