What is targeted therapy?
Targeted therapy is a kind of cancer treatment that’s focused on genetic changes or mutations that turn healthy cells into cancer cells. Targeted therapy helps healthcare providers treat cancer cells without hurting healthy cells.
How does target therapy works?
Cancer develops when the DNA in a cell mutates or becomes defective. Targeted therapy drugs are designed to bypass normal cells and act on specific targets-some are mutations on the surface of cancer cells, others are inside the cell. Once they reach their target, these drugs may:
• Shut down signals that allow cancer cells to grow
• Prevent cancer cells from making new blood vessels, which feed tumors
• Stop production of hormones that may help tumors grow
• Repair the ability of cells to shut down if they are defective
• Carry radiation or chemotherapy drugs directly to the mutated cell
