Abstract
The recent data concerning the relationship between psychosocial factors and the incidence of cancer have been reviewed covering life events, personality factors, psychiatric diagnoses, and loss-separation-hopelessness. The multiple methodological and design problems in this area of investigation are the factors that stand out and make interpretation difficult. Nevertheless, an association between oncogenesis and a number of factors such as extraversion, neuroticism, and lack of closeness to family is suggested. Many studies raise additional questions without providing definitive answers.
