How do Cancer Cell Receptors Contribute to Tumor Growth?
The primary way cancer cell receptors contribute to tumor growth is by disrupting normal cellular signaling pathways. For example, receptors like HER2 (Human Epidermal Growth Factor Receptor 2) and EGFR (Epidermal Growth Factor Receptor) can become overactive, sending continuous signals that promote cell division and inhibit apoptosis (programmed cell death). This leads to the rapid proliferation of cancer cells and the formation of tumors.
