The Canadian Cancer Society's Reach to Recovery program provides one-on-one support for breast cancer patients that is delivered by breast cancer survivors. Professionally-led social support programs have generally been found to influence positively the quality of life of cancer patients. However, there is a lack of evidence on the benefits of one-on-one peer support programs. An evaluation of the Reach to Recovery program was completed in 1995 to determine if cancer patients who received the program were satisfied with the program and to determine if participation in Reach to Recovery affected the quality of life of program participants compared to patients who did not receive the program. We found that Reach to Recovery program participants were generally satisfied with the program they received and that the program has incremental benefits to the quality of life of patients with breast cancer. Peer-led, volunteer breast cancer support programs can be effective in enhancing the quality of life of breast cancer patients.
