HOW MANY SURVIVORS HAVE FEAR OF RECURRENCE (FOR) , AND HOW LONG DOES IT LAST?
Some level of FOR is reported by almost all cancer survivors, with estimates of prevalence as high as 97%1. Although one may assume that FOR would decrease over time as risk of recurrence decreases (for most types of cancer) over time, levels of FOR among survivors have been shown to remain steady over time. For example, approximately 26% of long-time (over 5 years) breast cancer survivors report moderate to high levels of FOR2.
WHO IS AT HIGHEST RISK FOR HIGH LEVELS OF FOR?
From the perspective of a healthcare provider, it would seem logical that those most at risk for high levels of FOR would be survivors whose risk of recurrence was higher due to clinical factors, such as having a cancer that was particularly aggressive or was diagnosed at a later stage. But studies have demonstrated that the rather than objective clinical assessment of the risk of recurrence, the survivor’s subjective experience of cancer treatment1, in addition to psychological factors and sociodemographic variables, combine to impact their perception of their risk of recurrence.
Higher levels of FOR are associated these factors:
- Age: for women, being younger, especially those with young children3
- Education: having a lower level of education4
- Location: living in a rural area5
- Having poorer levels of overall health6
- Experiencing physical symptoms considered to be after-effects of cancer treatment, including pain and fatigue6-7
- Perceiving they don’t have strong enough coping skills to deal with the threat of recurrence8
- Having high levels of anxiety and believing that anxiety is both helpful and uncontrollable9
- Being depressed10 or having an anxiety disorder11
- Identifying as a “tumor patient”10
WHY DOESN’T FOR DECREASE OVER TIME? AND WHY AREN’T LEVELS OF FOR CORRELATED WITH DISEASE SEVERITY?
It does seem odd that FOR doesn’t decrease over time, and that levels aren’t associated with severity of disease. Healthcare practitioners may conceptualize risk of recurrence in objective terms of specific type of disease, grade, stage, and effectiveness of treatment. But for the general population of cancer survivors who do not have a medical background, FOR may be based more on the subjective experience of cancer treatment and the factors mentioned above than on medical facts. In fact, studies have documented that often survivors do not have an accurate understanding of their risk for recurrence5. Also, as time passes the accuracy of perception of risk for recurrence decreases, and higher levels of anxiety are associated with an overestimation of risk of recurrence12.
