A new study by researchers at Johns Hopkins University School of Medicine found that of the 31 cancers studied, only nine were found to be linked to lifestyle or genetic faults. The majority of cancers are due to “bad luck,” which in scientific terms means “random mutations arising during DNA replication in normal, noncancerous stem cells.” So most cancers are beyond our control. Do you find that comforting? I do, especially when faced with what often feels like an endless list of things to do or not do, or eat and not eat, all in the name of health! The research was published in the journal Science.
