Miley Cyrus was one of the many musicians who participated in the Annual Concert for Hope.

The profits from this concert go to help research cancer cures. Miley know how important it is to support organizations like these and that's why she is giving one dollar for every ticket she sold to the concert to cancer treatment centers.

Miley isn't only giving money, but also giving her energy. In the video you will see one of the cancer victims on stage with Miley. The girl is very ill with this disease.
