Social isolation and related stress could contribute to human breast cancer susceptibility, research from a rat model to identify environmental mechanisms contributing to cancer risk shows. The researchers found that isolation and stress result in a 3.3-fold increase in the risk of developing cancer among rats with naturally occurring mammary tumors. The research establishes, for the first time,

Social Isolation Worsens Cancer, Mouse Study Suggests
Using mice as a model to study human breast cancer, researchers have demonstrated that a negative social isolation causes increased tumor growth. The work shows -- for the first time -- that social isolation is associated with altered gene expression in mouse mammary glands, and that these changes are accompanied by larger tumors. This novel finding may begin to explain how the environment affect
