Racial disparity exists in various diseases that occur in human. In particular, the incidence and severity of Prostate Cancer is greater in black men than in white men in the United States. There are intrinsic biological differences that account for the differences in disease development and progression, but these differences are under-studied. Socially, cultural beliefs, as well as, inherent biases and systemic racism contribute to disparities in diagnosis, treatment, and prognosis of prostate cancer in black men on the macrolevel. However, at the biomedical and microlevel, an under appreciation or lack of awareness of the significance of ethnic and racial biological differences has resulted in inadequate diversity in bio-specimens and cell-line models in in vitro research.
Precision medicine is a growing field of interest in the treatment of diseases like cancer, where medicine and therapeutic intervention is tailored to the individuals genotype. However, with that, it is necessary to examine how ethnicity and race influence pathogenesis and progression of a disease, as well as, responsiveness to therapeutic intervention. Currently, the majority of biological samples that are collected from patients are collected from those who are classified as white or of European ancestry. Continue reading
