Researchers have found that epigenetic changes to DNA are associated with aging in disease-free breast tissues and are further altered in breast tumors. Epigenetic changes describe heritable alterations caused by mechanisms other than by changes in DNA sequence. The discovery illustrates how cancer and aging are tightly interconnected processes by identifying epigenetic alterations present in the normal aging breast that may increase disease risk in cancer-free individuals.
