Study: Breast, ovarian cancer may be linked in origin

BOSTON – Breast cancer and ovarian cancer may have similar origins, according to a study published last month in the International Journal of Molecular Sciences by Boston University School of Medicine researchers.
"Though breast and ovarian cancer are distinctly clinically different, our analysis uncovered many overlaps, particularly with respect to genetic and epigenetic alterations," said Dr. Sibaji Sarkar, an instructor of medicine at Boston University School of Medicine and an author of the study, referring to a process in which genetically identical cells express their genes differently, causing different outcomes.
