Is there a cure for anemia?

Depends on the cause: Anemia is a low red blood cell (rbc) count; this can also be defined by a low hemoglobin level, which is the protein that carries oxygen in the rbc. Anemia is either due to decreased production of rbcs (ie dietary) or increased destruction/loss (ie bleeding). Many of these causes are treatable/curable, but require diagnosis first.

Yes: The cause of anemia has to be determined. Many causes of anemia are curable.
