Background/Objectives: With improved technology and cancer treatments, the number of cancer survivors is growing. However, many cancer survivors experience long-term effects of cancer and its treatment, leading to a high health burden and poorer quality of life (QoL). A growing body of literature has explored the relationship between sociodemographic variables and QoL among cancer patients, although findings remain mixed. This study aims to assess the impact of social factors—role functioning, social functioning and social support—on the QoL of Icelandic cancer survivors diagnosed between 2015 and 2019, stratified by gender and cancer type (breast, prostate and colorectal cancer). Method: This study is a secondary analysis study, using data from a cross-sectional study conducted by the Icelandic Cancer Society in 2020–2021. In total, 1200 cancer survivors participated. Results: Multiple regression showed that less depressive symptoms, higher role and social functioning, better instrumental social support, higher educational attainment and income, less financial difficulties and lower age were significantly associated with higher QoL among participants. Conclusions: cancer survivors’ global health status/QoL is highly influenced by role functioning and depression symptoms, while other predictive factors, including social functioning, social support, education and income, vary by gender and cancer type.
