Breast cancer type prevalent among black women: Assessing risks and prognosis
In the United States, Black women are more likely to be diagnosed with and die from Triple-Negative Breast Cancer (TNBC) compared to their white counterparts. This disparity is due to a complex interplay of biological and social factors.
Biologically, Black women have a higher prevalence of aggressive tumor characteristics, such as mutations in the TP53 tumor suppressor gene, which leads to rapid cell growth and more aggressive cancer. Additionally, Black women with TNBC show distinct immune cell profiles that may impact survival but are not yet fully understood.
Socially, disparities in access to healthcare, insurance coverage, and timely treatment contribute significantly to higher mortality rates. Black women are more likely to experience higher rates of obesity, diabetes, and other chronic conditions that elevate breast cancer risk. Factors like income disparity, limited access to nutritious food, and neighborhood deprivation further exacerbate risks and impact treatment outcomes.
Research indicates that the prevalence of TNBC among Black women varies based on socioeconomic factors and treatment variables. Black women are more than twice as likely as white women to be diagnosed with TNBC, an aggressive subtype that often occurs at younger ages and spreads rapidly.
Obesity, which disproportionately affects Black women, increases breast cancer risk through inflammatory and metabolic pathways; social determinants like income gap and lack of access to healthy food worsen this risk factor. Genetic differences, such as a higher frequency of TP53 mutations in Black women, impair tumor suppression and contribute to tumor aggressiveness.
Systemic racism, communication issues with healthcare professionals, less likely to receive the appropriate standard of care, difficulties with travel to access care, financial struggles, and difficulties taking time off work are factors that may contribute to disparities in care and treatment for Black women with breast cancer.
A study found that breast cancer mortality rates are 40% higher for Black women than for white women in the US, with potential factors including genetics, health behaviors, social structures, income, insurance, and treatment. Addressing these disparities requires integrated approaches targeting both healthcare delivery and the broader social determinants of health.
It's important to note that a diet rich in vegetables, fruits, lean proteins, and whole grains is recommended for those experiencing breast cancer, but there is no specific diet for those with TNBC. Anyone unhappy about the response they get from a healthcare professional should consider seeking a second opinion, if possible.
