Helen Mirren and her husband, Taylor Hackford, are speaking out about the death of Taylor's son Rio Hackford.

In a joint statement on Tuesday, the married couple said Rio, 51, died of "uveal melanoma, a very aggressive and rare form of cancer."

The couple, in their statement to People magazine, encourages everyone reading about Rio's death "to get their eyes tested once a year, which might save their loved ones from this cancer."
