Abstract PO-093: Circulating tumor DNA (ctDNA) from peripheral blood is detectable among Ghanaian breast cancer patients

Cancer incidence is rising and mortality rates are high in Africa, where access to molecular pathology is limited. Analysis of cancer-related mutations in circulating tumor DNA (ctDNA) from cell-free DNA (cfDNA) that is shed into the bloodstream by tumor cells could be transformative to the African continent and provide new molecular insights. Using samples collected from the Ghana Breast Health Study we tested whether whole-genome sequencing...
