Been treated with monoclonal antibodies?

For example, if a patient has cancer and doctors want to treat it with an mAbs therapy, they must first identify the antigens on cancer cells and then make appropriate antibodies in the lab to target them. When an antibody binds to the cell, it serves as a flag to attract disease-fighting molecules or as a trigger that promotes cell destruction by other immune system processes. Despite being an efficient ally to the immune system, the mAbs therapy is quite exclusive as it hunts only one type of enemy. The third type is immunoglobulin M (IgM), which the body produces first when fighting an infection.
