Vrouwen die de diagnose  borstkankerkrijgen en die alles alleen moeten verwerken en geen steun krijgen van familie en/of vrienden hebben veel grotere kans te overlijden dan vrouwen die wel steun en support krijgen van familie en vrienden en/of professionele hulp krijgen. Onafhankeljk van stadium van de ziekte want stadia varieerden van stadium I tot IV. Aldus een deelstudie onder  2835 vrouwen met borstkanker stadium I tot IV  uit de grote Nurses Health Study. De studie naar dit onderwerp liep 10 jaar van 1992 tot 2002.  Aansluiting bij b v. een kerkgenootschap had geen invloed op risico van overlijden. Hieronder het abstract van de studie al gepubliceerd maart 2006 in Clinical Oncology.

PURPOSE: We prospectively examined social ties and survival after breast cancer diagnosis.

PATIENTS AND METHODS: Participants included 2,835 women from the Nurses' Health Study who were diagnosed with stages 1 to 4 breast cancer between 1992 and 2002. Of these women, 224 deaths (107 of these related to breast cancer) accrued to the year 2004. Social networks were assessed in 1992, 1996, and 2000 with the Berkman-Syme Social Networks Index. Social support was assessed in 1992 and 2000 as the presence and availability of a confidant. Cox proportional hazards models were used in prospective analyses of social networks and support, both before and following diagnosis, and subsequent survival.

RESULTS: In multivariate-adjusted analyses, women who were socially isolated before diagnosis had a subsequent 66% increased risk of all-cause mortality (HR = 1.66; 95% CI, 1.04 to 2.65) and a two-fold increased risk of breast cancer mortality (HR = 2.14; 95% CI, 1.11 to 4.12) compared with women who were socially integrated. Women without close relatives (HR = 2.65; 95% CI, 1.03 to 6.82), friends (HR = 4.06; 95% CI, 1.40 to 11.75), or living children (HR = 5.62; 95% CI, 1.20 to 26.46) had elevated risks of breast cancer mortality and of all-cause mortality compared with those with the most social ties. Neither participation in religious or community activities nor having a confidant was related to outcomes. Effect estimates were similar in analyses of postdiagnosis networks.

CONCLUSION: Socially isolated women had an elevated risk of mortality after a diagnosis of breast cancer, likely because of a lack of access to care, specifically beneficial caregiving from friends, relatives, and adult children.
