Cancer cell biology is an academic and research field dedicated to the investigation of the fundamental cellular and molecular mechanisms that drive the initiation, progression, and metastasis of cancer. It examines the genetic, epigenetic, and environmental factors that lead to uncontrolled cell proliferation, altered differentiation, resistance to apoptosis, and the complex interactions within the tumor microenvironment, aiming to elucidate the biological basis of malignancy and identify potential therapeutic strategies.
