The Who, What, Where, When and Sometimes, Why.

Social support and breast cancer survival

This summary table contains detailed information about research studies. Summary tables are a useful way to look at the science behind many breast cancer guidelines and recommendations. However, to get the most out of the tables, it’s important to understand some key concepts. Learn how to read a research table.

Introduction: You get social support through interactions with others, including your family, friends and co-workers.

Social support may be linked to increased quality of life after breast cancer treatment [1-4]. However, it’s unclear whether social support is linked to improved survival.

Randomized controlled trials don’t show a survival benefit from support groups for women with breast cancer (see our research table on support groups and survival).

However, some large cohort studies suggest women with more social support have better survival than those with less social support.

The differences in results may be due to the types of social support studied.

Cohort studies have mostly studied the social support people get from social networks, such as friends and family. Randomized trials have mostly studied social support from strangers, such as support groups.

Further studies are needed to know whether there’s a difference between these types of social support and breast cancer survival.

Study selection criteria: Prospective cohort studies with at least 200 participants and meta-analyses.

* Findings showed women with higher levels of social support had lower rates of death due to any cause compared to women with lower levels of social support. Rates of death due to breast cancer were similar between the groups.

† All women in this study were ages 65 and older.

‡ A fourth cohort study in this meta-analysis found no difference in breast cancer survival between women with and without social support.
