Healing of Lydia Brosse

During 18 months before her pilgrimage, Lydia underwent several operations for multiple bone and subcutaneous abscesses. She was exhausted, emaciated (under 40 kg), in pain, and anaemic. There was no improvement during the pilgrimage. On the return journey from Lourdes to Saint-Raphael, under the doctor's eyes on the train, she found the strength to raise herself—and her fistulae were discovered to be closed. The Bishop of Coutances officially recognized the cure as miraculous on 5 August 1958.

The Lourdes Medical Bureau gathered documentation; the International Medical Committee (C.M.I.L.) affirmed the cure was inexplicable in the current state of medical knowledge. The Bishop of Coutances recognized it on 5 August 1958. Tuberculosis was the leading cause of death before antibiotics. Rapid, complete cure without drugs is medically unexplained.
