Cancer epigenetics

Cancer epigenetics is the study of changes in gene expression that do not involve alterations to the DNA sequence itself. Instead of mutations, cancer can arise when certain genes are turned on or off due to chemical modifications, like adding or removing chemical tags. These changes can influence cell behavior, leading to uncontrolled growth and tumor formation. Understanding these epigenetic changes helps researchers develop targeted therapies and diagnostics, providing insights into cancer prevention and treatment strategies.
