- Abstract: Objective To investigate the effects of emotions(subjective well-being,depressed effect,worry,and guilt)on cancer(colorectal cancer,hepatic cancer,thyroid cancer,lung cancer,and breast cancer).Methods Two-sample bi-directional Mendelian randomization(MR)method was adopted.All data were based on summary data from genome-wide association studies(GWAS).Inverse variance weighting(IVW)was used to generate the main results,and weighted median(WM)and MR-Egger methods were employed to calculate supplementary results.The outcome measure was odds ratio(OR),and sensitivity analysis was conducted.Results For depressed effect,a significant association with lung cancer(OR=1.005,95％CI:1.001-1.009,P=0.015)was found.For worry,a significant association with breast cancer(OR=1.199,95％CI:1.011-1.423,P=0.038)was observed.For guilt,a significant association with thyroid cancer(OR=2.083,95％CI:1.080-4.017,P=0.029)was identified.After removing all potentially pleiotropic SNPs detected by MR PRESSO,the association between worry and breast cancer showed no statistical difference(P=0.064),while the association between worry and colorectal cancer remained significant(OR=0.739,95％CI:0.571-0.956,P=0.021).No causal relationship was found between cancer and emotions.Conclusion There is a causal relationship between depression and increased lung cancer incidence,guilt and increased thyroid cancer incidence,as well as anxiety and decreased colorectal cancer incidence.
