How do Biological Signals Contribute to Cancer Development?
Cancer often arises due to disruptions in normal cellular signaling pathways. For instance, mutations in genes that encode for growth factors or their receptors can lead to uncontrolled cell proliferation. Similarly, alterations in signaling pathways like the PI3K/AKT or MAPK pathways can promote oncogenesis. These disruptions can result from genetic mutations, epigenetic changes, or environmental factors.
