Great news to report.
In the providence of God, the serious GI bleed revealed the presence of a polyp turned tumor which caused the bleeding. Had I not had the bleeding, I would never have known the nasty little polyp was in there growing and turning cancerous. The doctor was able to remove the polyp/tumor, and found nothing outside. The pain, while great, is bearable and the doctors anticipate a full and complete recovery with little to no change in diet and lifestyle.
We felt your prayers and are deeply moved by so many thoughtful well-wishes. I will remain hospitalized a couple of days and may even be at church sooner than expected.
God is good.
