Analysis of relationship between psychological stress and cancer incidence, PSCA

This study explores how long-term stress, and adverse childhood experiences predict chances of getting cancer. First, we want to see if past stress can predict cancer incidence and changes in HRV, blood pressure, and hair stress hormones. Second, we're testing if HRV or hair stress hormones act as a mediators between past stress and the risk of getting cancer.
