There have been numerous studies on personality traits, health-related behaviors, and the risk of cancer, but the findings do not concur since some agree that personal characteristics are the cause of cancer while others do not (Lemogne, et al., 2013). According to Hansel, Floderus, Frederiksen & Johansen (2005), their study based on the same topic, and had the objective to establish if personality traits were a risk for cancer. The team established a cohort study in a controlled environment (Hansen, Floderus, Frederiksen, & Johansen, 2005). The study approached 29,565 Swedish twins and their identities were retrieved from the Swedish Twin Registry (Hansen, Floderus, Frederiksen, & Johansen, 2005). Moreover, their target age was between 15 and 48 years. According to the background information, the starting year of reference and selection of the twins was 1973 when twins in Sweden completed the filling survey questionnaires on their personalities and health-related behavior.

The team used an Eysenck Personality Inventory to show their neuroticism and extroversion as the personal properties. Also, the Cox proportional hazard system was used to measure the quantitative hazard relation of their neuroticism and extroversion to establish the link between human personality and risk for cancer in all the twin pairs (Hansen, Floderus, Frederiksen, & Johansen, 2005). The analysis was done for six various etiological sub-disciplines of cancer. The groups comprised of hormone organ cancer, virus and immune cancer, and digestive biological structure of cancer among others (Hansen, Floderus, Frederiksen, & Johansen, 2005). The results were later cross-referenced to the Swedish Cancer Registry data and it was found that personality traits, especially neuroticism and extroversion had no links to any of the cancer groups (Hansen, Floderus, Frederiksen, & Johansen, 2005). Bearing that in mind the group created a hypothesis leaving the question open for future research. Moreover, Nakaya et al. (2006), found out that neuroticism and risk of cancer were linked, and gender was a possible risk of death.
