When I shared with my sons they were very shocked, although supportive. At the time my youngest was in 5th grade and he was not quite sure what this meant, but he assumed the worst. One of his classmates dad took time to share with my son his mother was diagnosed with cancer when he was elementary school as well and she was still alive. My son was able to ask him questions and my son knew his mom. The conversation gave him so much peace and he was confident that everything would be just fine.
