In one of her last public appearances, Carson testified before President John F. Kennedy's Science Advisory Committee. The committee issued its report on May 15, 1963, largely backing Carson's scientific claims. Following the report's release, she also testified before a United States Senate subcommittee to make policy recommendations. Though Carson received hundreds of other speaking invitations, she was unable to accept the great majority of them. Her health was steadily declining as her cancer outpaced the radiation therapy, with only brief periods of remission. She spoke as much as she was physically able, however, including a notable appearance on "The Today Show" and speeches at several dinners held in her honor. In late 1963, she received a flurry of awards and honors: the Audubon Medal (from the National Audubon Society), the Cullum Geographical Medal (from the American Geographical Society), and induction into the American Academy of Arts and Letters.
