Several strategies are employed to achieve selectivity in cancer treatments:
Targeted Therapies: These drugs are designed to target specific molecular markers present on cancer cells. For example, HER2 inhibitors specifically target HER2-positive breast cancer cells. Monoclonal Antibodies: These are immune system proteins created in the lab that can bind to cancer-specific antigens, marking them for destruction by the immune system. Small Molecule Inhibitors: These inhibitors can penetrate cells and interfere with specific proteins that promote cancer growth. Immunotherapy: This treatment boosts the body's natural defenses to fight cancer, such as by using checkpoint inhibitors that release the brakes on the immune system.
