The antibody delivers radioactivity directly to cancerous B cells and can be used to treat some types of non-Hodgkin lymphoma. Treatment with this type of antibody is sometimes known as radioimmunotherapy (RIT).
What monoclonal antibodies are in use for cancer now and how do they work?
Naked monoclonal antibodies
They work by themselves. These are the most common type of mAbs used to treat cancer. Most naked mAbs attach to antigens on cancer cells, but some work by binding to antigens on other, non-cancerous cells, or even free-floating proteins. Naked mAbs can work in different ways.
What are the uses of monoclonal antibodies in disease treatment?
Some monoclonal antibodies can trigger an immune system response that can destroy the outer wall (membrane) of a cancer cell. Blocking cell growth. Some monoclonal antibodies block the connection between a cancer cell and proteins that promote cell growth — an activity that is necessary for cancer growth and survival.

How do monoclonal antibodies detect cancer?
Monoclonal antibodies can be designed to bind specifically with these antigens. When injected into a person’s body, the monoclonal antibodies will bind with these cancer cells and clump them together. This makes it easier to identify a cancerous tumour , which can then be treated or removed.
