Saint Peregrine is considered by the Catholic church the patron saint of cancer patients and those suffering other serious or incurable illnesses. One prayer to him by the Franciscan Friars of the Atonement reads, "Saint Peregrine, we confidently turn to you in times of suffering and illness, we ask for your powerful intercession before our God in Heaven, to protect us from all cancerous diseases and illnesses."
Worshippers may offer several different prayers to Saint Peregrine in the form of novenas or devotions. Petitions often request healing, strength to endure illness, and signs of God's love. Followers look to the saint as a model of Christian faith and trust in God during illness.
Believers may submit requests for prayer and inclusion in a special mass on their behalf at both the National Shrine of Saint Peregrine in Chicago, Illinois and the Saint Peregrine Shrine at the Grotto in Portland, Oregon.
Born in Italy in 1260, Saint Peregrine Laziosi was an ordained priest who aided the poor and sick. He was allegedly cured of a cancerous infection of his left leg after seeing a vision of Jesus reaching out to touch his limb on the night before he was to have the leg surgically amputated.
