It may not be too early to start praying:
"O Lord Jesus Christ, our Savior, Physician of souls and bodies, who didst become man and suffer death on the Cross for our salvation, and through thy tender love and compassion didst heal all manner of sickness and affliction; do thou O Lord, visit Father Ambrose in his suffering, and grant him grace and strength to bear this sickness with which he is afflicted, with Christian patience and submission to thy will, trusting in thy loving kindness and tender mercy. Bless, I pray thee, the means used for his recovery, and those who administer them. Have compassion on Father Ambrose, and let mercy and justice meet; and deliver him from this sickness and suffering he is undergoing. Grant that his sickness may be the means of his true repentance and amendment of his life according to thy will, that he may spend the rest of his days in thy love and fear: that his soul, being helped by thy grace and sanctified by thy Holy Mysteries, may be prepared for its passage to the Eternal Life, and there, in the company of thy blessed Saints, may praise and glorify thee with thy Eternal Father and Life-giving Spirit. Amen."
