If a mutation in the EGFR receptor allows continuous downstream signaling, even without growth factor binding, which consequence follows regarding cancer cell proliferation?

💡 Explanation

Continuous EGFR signaling due to mutation bypasses normal growth factor-dependent regulation of cell division; because the receptor is always active, it promotes unregulated cell cycle progression. Therefore, uncontrolled division occurs, rather than controlled division or effects on metabolic pathways.
