I am so sorry to hear this news, but there are new medications and procedures being created every day. It sounds like he's not sure if he has the same type of cancer if he used the word "might". Until the diagnosis has been confirmed, no one can be sure of what he has. If he has cancer, I pray that they have caught it early and can help him.
A this very moment, he is facing reality and coming to realize that each and every day is a gift. We are told throughout our life that Christmas is a magical time of the year and miracles do happen during this time. I would suggest praying for him and asking the man upstairs to help this man heal and reconnect w/his family and friends during this time. This holiday season is a time for reflection of the past and future. The present is the gift that we all need to use wisely each and every day.
For now, sit quietly and the answers will come. Keeping all of you in my thoughts and prayers.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
