Pope Leo has been diagnosed with cancer and is in the hospital, unsettling Catholics in Hawaii and around the world.

• The pope is expected to stay in the hospital about a week while doctors treat him.
• Cancer doctors are weighing what his treatment and recovery will look like.
• His planned trip to South America next month is still on the schedule for now.
• At Saint Peter and Paul Church in Honolulu, parishioners gathered at Mass to pray for him, saying they need his guidance.

Outlook: The Vatican will likely give more detail on his treatment in the coming days, and the South America trip is the first test of whether his health holds up.
