Abstract Personal medicine is based on purposeful treatment that, unlike traditional therapies, considers a person's genetic structure and medical history before establishing a treatment regimen. This science has made possible the improvement of "pharmacogenomic" knowledge, which identifies individuals who respond to a particular treatment based on their genotype information. The findings of the Cancer Genome Atlas Network show that each molecular endorsement of each BCis unique. Also, different responses to a given medication regimen have been reported among a similar group of breast cancer. Thus, personal medicine plays a role in the care of patients with breast cancer, in which a person's characteristics, including genetic characteristics, guide clinical decisions and are effective in choosing the right treatment for the patient at the right time.

Abstract Mitochondria are the extra-nuclear source of DNA in cells and play an important role in cell death susceptibility,  oxidative stress regulation, metabolism, and signaling in normal cells. Because of this, its dysfunction can contribute to the progression of cancer and metastasis. Also, mtDNA mutations have been reported in many cancers, followed by altered mitochondrial activity and cellular signaling . This increase in mtDNA mutation is due to the proximity of the genome to the OXPHOS system which are thought to be more in extent than mutation nuclear. These mutations do not inactivate energy metabolism but change its state. Therefore, it is not surprising that the function of mitochondria is vital for cancer cells, in addition to understanding the mechanisms of mitochondrial function in the process of tumor formation and cancer progression is essential for cancer treatments.
