Epidermal Growth Factor Receptor

Epidermal Growth Factor Receptor (EGFR) is a protein found on the surface of certain cells, especially skin and tissue cells. It acts like an communication antenna, receiving signals from the environment to tell cells when to grow, divide, or repair. When EGFR functions normally, it helps maintain healthy tissue. However, sometimes it becomes overly active or damaged, leading to uncontrolled cell growth, which can contribute to cancers like lung or skin cancer. Understanding EGFR is important for developing targeted treatments that inhibit its activity in cancer therapy.
