Genetic landscape of breast cancer and mutation tracking with circulating tumor DNA in Chinese women

cfDNA in healthy individuals and breast cancer patients. (A) Amount of cfDNA extracted from all healthy individuals and cancer patients of different stages. (B) Mutant allele frequency of cfDNA detected in patients with different cancer stages. The means for each group are represented by the black lines in each column. cfDNA, cell-free DNA.
