Physical and psychosocial functioning and adjustment to breast cancer. Long-term follow-up of a screening population

Abstract

The effects of age, recency of breast cancer (BC) diagnosis, and severity of the disease on adjustment outcomes were investigated in a sample of 349 women from the 10,059 women screened for BC by the University of Michigan Breast Cancer Detection Demonstration Project between 1974 and 1981. In the 1985 follow‐up, data were collected from the 173 surviving BC patients who had invasive BC, and from a matched control group of 176 women who were asymptomatic of BC. Fifty‐five percent of the BC patients were 5 years past diagnosis and treatment at the time of data collection. The BC patients group as a whole did not differ from the asymptomatic control group on indicators of mental health, social and psychological well‐being, or physical functioning. However, the BC group reported a greater number of diagnosed medical conditions that limited their activities, and taking more medications, than the asymptomatic group. Within the BC group, severity and recency of the cancer had strong independent adverse effects on several of the indicators of mental health and physical functioning. Advanced age had the same main effects in both groups: greater number of medications and diagnosed medical conditions that cause limitatieas in activities, but, in contrast, better mental health and well‐being. Age had interactive effects with the recency and with severity of BC: more recent and severe cases of BC appeared to produce particularly serious difficulties in psychological adjustment for younger patients, and particularly serious medical problems and physical difficulties in adjustment for older patients.
