Article Abstract
Previous studies have suggested the missense variant NM_000051.4(ATM):c.7271T>G is associated with a high risk of breast cancer (BC), but the magnitude of the association, and the associations with other cancer types, are unclear. Cancer associations were evaluated using sequence data linked to cancer registration data (348 488 participants, 56 640 cancer cases) from UK Biobank (UKB), and targeted sequence or genome-wide array data (126 428 cases, 115 495 controls) from the Breast Cancer Association Consortium (BCAC). The magnitudes of the association of c.7271T>G with invasive BC were similar using UKB (relative risk (RR): 4.57, 95% CI: 2.25 to 9.30, p=2.7×10) and BCAC (OR: 4.11, 2.05 to 8.26, p=6.9×10). In UKB, c.7271T>G was associated with increased risks of prostate cancer (4.84, 2.27 to 10.33, p=4.54×10), and any other cancer (males 2.79, 1.33 to 5.85, p=0.0066; females 3.15, 1.49 to 6.63, p=0.0026). Estimated cumulative risks of all cancers to age 80 years were 87% in males (prostate cancer 43%) and 84% in females (BC 43%). The estimated RRs are consistent with c.7271T>G being associated with a risk of more than twice that for Ataxia-Telangiectasia Mutated protein-truncating variants, for all cancers. These data justify specific management of c.7271T>G carriers.

Background: Breast cancer is the most common cancer among women and a leading cause of mortality in Europe. Early detection through screening reduces mortality, yet participation in mammography-based programs remains suboptimal due to discomfort, radiation exposure, and accessibility issues. Thermography, particularly when driven by artificial intelligence (AI), is being explored as a noninvasive, radiation-free alternative.

Objectives: To analyze the temporal trend and identify spatial clusters of breast cancer mortality in Paraná state between 2012 and 2021.
Methods: This was a time series study, with spatial analysis of breast cancer mortality rates in the 399 municipalities of Paraná. Data were selected from the Mortality Information System.

The objective of this study was to analyze the characteristics of avoidable mortality in the population aged five to 69 years living in the city of Pelotas/RS, comparing it with the rest of the state of Rio Grande do Sul, from 2000 to 2021. An ecological study was conducted analyzing avoidable mortality coefficients according to sex and age, from 2000 to 2021. The data source was the Mortality Information System, and the trend analysis was performed using Prais-Winsten regression, with standardization of coefficients.

This study aimed to evaluate mortality due to female breast cancer attributable to overweight and obesity and to estimate the number of preventable deaths with a reduction in the Body Mass Index in Brazil. An ecological study was carried out with investigation of information on overweight, obesity, sociodemographic characteristics based on a national survey carried out in 2013-14; breast cancer mortality rate in 2019 using the Online Atlas of Mortality and Relative Risk Meta-Analyses. The Potential Impact Fraction analysis was carried out, considering the following counterfactual scenarios related to the reduction in BMI: Scenario A - population contingent of women that make up the prevalence of overweight and obesity now composes the prevalence of eutrophy; Scenario B - population contingent of women that make up the prevalence of overweight starts to make up the prevalence of eutrophy; Scenario C - population contingent of women that make up the prevalence of obesity becomes part of the prevalence of overweight.
