Epidemiology researchers in one study exploring the effects of social support on cancer survival, interviewed 244 breast cancer patients. The patients were asked how many people they confided in during the three months post surgery. Then they were followed for several years. The seven-year survival rate for the patients who had not confided with anyone during that three-month post surgery period was 56 percent. The survival rate for those who had confided in one person was 66 percent. Those who had confided in two or more people had a 76 percent survival rate.

In another study of 514 women, 239 were diagnosed with breast cancer. One of the results of this study was that those with the least social support were nine times as likely to develop cancer following a stressful life event. In fact, most psychooncology studies have found a positive correlation between survival time after cancer diagnosis and the amount and quality of social support.
