Targeted therapy utilises drugs or other substances that block the growth of cancer by targeting and interfering with the tumor growth and progression by attacking specific targets in cancer cells. They induce the death of the cancer cells by destroying those targets.
Examples of Targeted Therapies include Angiogenesis Inhibitors, EGFR Inhibitors and TKI blockers. Angiogenesis inhibitors block the formation of new blood vessels in cancer cells. New blood vessels form naturally in tumors, because they grow rapidly, and require new blood vessels for nutrition and oxygen. By preventing the formation of these blood vessels, the growth of the cancer can be slowed or inhibited.
