What is the role of targeted therapy in cancer treatment?
Targeted therapy involves drugs designed to interfere with specific molecules necessary for tumor growth and progression. Unlike traditional chemotherapy, which affects all rapidly dividing cells, targeted therapies hone in on molecular targets associated with cancer. Examples include drugs that inhibit the function of proteins like HER2 in breast cancer or BCR-ABL in chronic myeloid leukemia. These therapies can be more effective and less harmful to normal cells.
