For decades, cancer was seen primarily as a genetic disease—triggered by DNA mutations that disrupt cell growth. But recent breakthroughs in epigenetics have shifted that view. Scientists now recognise that chemical changes to DNA, such as methylation and histone modification, also play a critical role in how cancer develops, spreads, and responds to treatment. https://www.cd-genomics.com/epigenetics/resource-cancer-epigenome-diet-therapies-mechanisms.html
