Welcome to this forum, Janine.

My husband was also Stage IV. He is three and a half years out from treatment and doing very well. The treatment is rough, to be sure, but your family can do this. You might be surprsed at how your son rises to the occasion. I certainly saw that with my two daughters who were of similar age during treatment.

Ask any question you have here. There are some very knowledgable and caring people on this site, as you have probably already discovered.

Best to you,
Anita
