How does nano-robot treat cancer? It release gamma rays to kill cancer cell. It target cancel cells and deliver an antibody payload. It scans organisms and discover cancel cells, but not kill them. It changes the DNA sequence of cancel cell.

It targets cancer cells and deliver treatment specifically to those cells.

Explanation:

Nanorobots are are tiny machines that are designed to deliver drugs directly to cells and tissues requiring them. The idea behind this is to reduce or totally eliminate the negative side effects that conventional mode of administration of medication has on other healthy body systems and organs which sometimes make cancer treatment counterproductive and a nightmare to patients.

Also, with nanorobots directly supplying drugs to the targeted cells, the whole or most of the metabolic processes that are involved in the breakdown of drugs are bypassed and therefore this enhances the effectiveness and potency of such targeted drugs.

Another advantage of this is that drugs are delivered in the pure form and not mixed transport and preservative substances which may cause allergic reactions.

One of the challenges facing nanorobotics is the ability to make these tiny machines able to navigate the body and identify targeted cells and tissues but overall, it is a promising prospect.
