15yr old cancer patient

This is jack our son. He's 15. Jack is a lovable young man who has a wicked sense of humor, he's cheeky, funny and likes hanging out with his friends. Last year that all changed. Jack started complaining of his legs being sore to the point that he could hardly walk, so we took him to our local A&E where an x-ray was done, we were then told he was showing signs of juvenile Arthritis and was sent home with pain medicine. A day later he was still no better and was running a temperature. So we went back to our local hospital again were they ran tests, scans etc, a few hours later we were told that he had a mass in his abdomen. Biopsy was done and two weeks later in August 2019 Jack was diagnosed with stage 4 high risk neuroblastoma. To say it changed everything is an understatement. We were given a treatment plan of between 12-18 months, we are now 13months into treatment and the treatment he has had to date including a clinical trial hasn't really worked. He relasped during treatment. In october we were given the devastating news that its very unlikely that his disease will be cured. So we would like to do something special for him to lift his spirits abit as he doesn't get out and about as must as he used to.
