Abstract The aim of this study is the calculation of equivalent organ dose and estimation of lifetime attributable risk (LAR) of cancer incidence and mortality related to cardiac computed tomography angiography (CCTA) because the use of CT angiography as a noninvasive diagnostic method has increased. The organ dose has been calculated by ImPACT software based on the volumetric CT dose index (CTDIvol), and LAR of cancer risk incidence and mortality from CCTA has estimated according to the BEIR VII report. The median value of the effective dose was 13.78 ± 6.88 mSv for both genders. In all scanners, the highest median value for LAR of cancer incidence in males and females for lung cancer was 44.20 and 109.17 per 100 000, respectively. And in infants was 5.89 and 12 for lung cancer in males and breast cancer in females, respectively. Also, the median value of LAR of all cancer incidence from single CCTA in adult patients for males and females was 122 and 238 cases, respectively. Maximum LAR of cancer mortality in adults for lung cancer was 40.28 and 91.84 and in pediatrics was 5.69 and 8.50 in males and females, respectively. Despite many benefits of CTA in the heart disease evaluation, according to a high radiation dose in CCTA, to reduce the cancer risk: CCTA should be used cautiously, especially for pediatric and females.

The Relationship

The relationship between socioeconomic status (SES) and cancer is complex, dynamic, and evolving. Associations depend on SES measures, cancer type, sociodemographic factors including race/ethnicity, and historical trends. However, socioeconomic disadvantage is often associated with a higher risk of cancer, particularly cancers diagnosed at a late stage, as well as worse prognosis once diagnosed. Research on secular trends over the past 70 years has shown reversals of the socioeconomic gradient for lung and colorectal cancer consistent with differential trends by SES in patterns of smoking, diet, and obesity. Rates of these cancers are now currently higher in socioeconomically disadvantaged groups. SES is considered to be a “fundamental” determinant of health outcomes, and this appears true throughout the cancer spectrum—from cancer incidence to detection, treatment, and survival. Investigations over the past decade have increasingly considered the simultaneous impact of individual SES and area-level SES (as a contextual influence) on health outcomes.
