Cancer Survival

In several studies, supportive marriages have been shown to improve survival rates in people with cancer, including prostate, lung, and colon cancer. In a major study of 3.8 million cancer patients published in 2009, 58% of married people lived for 10 years post-diagnosis, compared with 52% of people who were never married, 46% of divorcees, and 41% of widows and widowers.

People who were separated from their spouses fared worst of all, with only 37% surviving for 10 years. The loneliness and unexpected stress of going through a separation may have a negative effect on the body's immunity, the study authors noted.
