Molecular targeted therapy: Treating cancer with specificity.

Molecular targeted therapies are revolutionized therapeutics which interfere with specific molecules to block cancer growth, progression, and metastasis. Many molecular targeted therapies approved by the Food and Drug Administration (FDA), have demonstrated remarkable clinical success in the treatment of a myriad of cancer types including breast, leukemia, colorectal, lung, and ovarian cancers. This review provides an update on the different types of molecular targeted therapies used in the treatment of cancer, focusing on the fundamentals of molecular targeted therapy, its mode of action in cancer treatment, as well as its advantages and limitations.
