Miss District of Columbia Allyn Rose, who made headlines by announcing plans to undergo a preventive double mastectomy after the competition to reduce her risk of breast cancer, was eliminated.

The competition winner will receive a $50,000 scholarship and is expected to embark on a yearlong speaking tour to advocate for her chosen cause and raise money for the Children's Miracle Network, the pageant's official charity.

The contestants all week have been on a tight schedule of rehearsals, media events and one-on-one interviews with the judges.

Among the preliminary winners were Miss Maryland and Miss Oklahoma. Miss Alabama won the $6,000 Quality of Life Scholarship for her commitment to community service.

The remaining women will face off in swimsuit, evening gown, talent and interview competitions.
