According to a new research, loneliness can increase risk of cancer. Research was conducted on rodents. Rodents that are kept alone developed more tumors of deadly type than rats living as a group.
The researchers say that the same may be true in humans. Experts in cancer say that more work and research is needed to prove such a link in humans.
In terms of survival, cancer patients who are depressed tend to fare worse. Previous research has found that social support can enhance health conditions for breast cancer patients.
In this study, researchers found that risk of breast cancer trebled with isolation and stress in sociable Norway rats.
Loneliness can send a person down a path toward bad health, and even more intense loneliness, studies have shown. But while some have assumed the culprit was a dearth of others to remind a person to take care of himself or herself, new research suggests there's a direct biological link between being lonely and ill health.
