8-530.7:

You have been treated with a radioactive drug.that was linked to an antibody.

Radioactive drugs emit radiation. The intention is for the radiation to damage pathologically altered cells in the body. Radioactive drugs are used for tumors, among other things. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant.

Depending on type, task and origin, the cells of the body have typical proteins on their surface. Pathologically altered cells sometimes have different proteins on their surface than healthy cells.

Antibodies are defense substances that are found in the body. However, antibodies can also be synthetically manufactured to treat certain illnesses. Antibodies recognize proteins on the surface of cells and bind to them. A certain antibody only ever binds to the matching protein.

A radioactive drug that was linked to an antibody was administered to you via a blood vessel. The drug spreads through the body with the blood. It accumulates where the antibody binds to the relevant protein. This is where the radiation emitted by the radioactive drug has its effect.
