Monoclonal antibodies are useful in treating cancer when radioactive materials or tumor-killing drugs are attached to them.How is it that these cancer-killing methods are delivered only to the tumor and not to other healthy cells?

Monoclonal antibodies are designed to specifically target and bind to a particular antigen found on cancer cells, which allows for targeted delivery of the attached tumor-killing drugs or radioactive materials. This specificity minimizes damage to healthy cells in the body. Antibodies do not stimulate T helper or cytotoxic T cells directly, although they can indirectly activate these immune cells by enhancing their ability to recognize and attack cancer cells.
