Hi Mandy, welcome to the forum, but sorry for the reason you are here. You haven't said a lot about your situation, or what exactly is going on with your husband, but it sounds like its' pretty serious. Kids are pretty resilient and certainly do pick up on what's happening in the home, so he likely already suspects something is going on with his Dad. How mature is he for 10 years old, and is he the only child? Is he a happy go lucky kid or more reserved and a deep thinker? How have you dealt with other situations that come up in every family over time? I realize that nothing this serious has happened up until now, but if you have made it a practice to tell him about other situations, you may be able to get some ideas from those experiences. He does need to be told that his Dad is ill, but he doesn't need all the details about his illness, and unless death is iminent, I don't think it needs to be raised at this point. If he asks though, and he just might, don't lie to him. Whatever you do tell him, always temper it with reassurance that you will be there for him no matter what happens. What does his Dad say about telling your son?

Further to this, your husband's treatment team may have some recommendations for you, or even have someone available to provide guidance in talking with children. In addition, there is a section here on the forum that gives some ideas in talking to children about cancer. It might help for you to contact the nurses at the phone number at the bottom of this page during business hours, or post your questions in the "Ask the Nurses" section. I would also suggest your advise his school teachers about what's happening so they can keep an eye on your son while he is at school.

I hope this helps somewhat. Don't forget to take care of yourself as you take this journey with your husband. Come back on the forum any time to communicate with others on here. It does help to write down your thoughts and feelings when going through something like this. 

Take care.

Lorraine
