Thank you for sharing this wonderful story of your son Chris. I also can relate to your wonderful experienced. My daughter who just turned 14 was diagnosed with Osteosarcoma. It was a very painful news that no parents would want to hear. Many thoughts and awful feelings going through our mind as a parent hearing your child has this dreadful disease. We were also given this option and my daughter made the decision to have it done. She is now one week post surgery and doing well. She started to do some physical therapy and some pain that comes and go. All in all she has a very good attitude and a strong determination. Thank you for sharing your story. Good luck to your son.
