PS to my above post. More important than where the cancer came from is where does one go from here on, and what is learned from the experience. Sherrie, your daughter has a great teaching opportunity and hopefully the kids will learn something! So many people just don't realize what the deal is. When I saw my dentist recently and told him about my son's cancer, the first thing he asked was "Does he smoke?" - and he looked surprised when I told him his age and that - No, he did not smoke.
