Accident – Death – Obituary News : : 1. Breast cancer risk assessment
2. Genetic factors breast cancer
A recent study published on May 13 identified twelve breast cancer genes in women of African ancestry, potentially leading to better risk prediction for the disease. The research, focusing on more than 40,000 women in the United States, Africa, and Barbados, revealed genetic differences in breast cancer risk between women of African and European descent. Some mutations were newly linked to the disease, while others previously associated with breast cancer in white women showed no correlation in this study. Black women in the U.S. have higher rates of aggressive breast cancers, highlighting the importance of genetic testing for all patients regardless of race.

Groundbreaking Study Identifies Breast Cancer Genes in Women of African Ancestry
A recent study published on May 13 has shed light on twelve breast cancer genes specific to women of African ancestry, marking a significant step towards better predicting their risk for the disease. This groundbreaking research has highlighted potential differences in risk factors between women of African and European descent.
Research Scope and Findings
The study involved more than 40,000 women of African ancestry across the United States, Africa, and Barbados, with a focus on 18,034 individuals diagnosed with breast cancer. The findings revealed certain genetic mutations that were previously unknown or weakly linked to the disease, indicating unique risk factors among women of African descent.
Significant Gene Mutation Discovery
One particular mutation identified in the study showed an exceptionally strong association with breast cancer, surpassing conventional findings in cancer genetics. Additionally, some genes known to increase breast cancer risk in white women did not correlate with the disease in women of African ancestry, underscoring the importance of population-specific research.
Impact on Breast Cancer Risk Assessment
By incorporating the newly identified genes alongside established risk factors like BRCA1 and BRCA2, researchers developed a more accurate breast cancer risk score specifically tailored for women of African descent. This advancement in risk assessment could potentially revolutionize early detection and prevention strategies within this population.
Triple-Negative Breast Cancer Risk
Of the abnormal genes discovered, six were associated with an elevated risk for triple-negative breast cancer, the most aggressive form of the disease. Previous studies have shown that black women have a significantly higher incidence of this type of breast cancer compared to white women, making these findings particularly significant in addressing health disparities.
Future Implications and Recommendations
While the newly identified gene variants show promise in enhancing breast cancer risk assessment, further evaluation is needed before their widespread adoption for testing. The American Cancer Society advocates for genetic testing in all patients, regardless of race, emphasizing the importance of equitable access to care and informed decision-making.
Overall, this study represents a crucial step towards understanding and addressing breast cancer disparities among women of African ancestry, paving the way for more tailored and effective healthcare interventions in the future.
