A method for treating a malignant tumor in a patient identifies tumor cells using a logical AND operation on antigens on the surfaces of the tumor cells. First and second antigens are determined to be present on the tumor cells. A first medication including a first antibody and a second antibody is administered to the patient. The first antibody is linked to a first dock, and the second antibody is linked to a second dock. In the patients body, the first antibody binds to a first antigen, and the second antibody binds to a second antigen. After the elapse of a first predetermined interval, a second medication is administered to the patient. The second medication forms a structured binding site when the second medication simultaneously binds to both the first dock and the second dock. After the elapse of a second predetermined interval, a third medication is administered to the patient. The third medication binds only to the structured binding site and activates immune cells of the patient.
