I was 39 when I was diagnosed and my family had just lost my Father to cancer just over 1 year prior.
I ran, and still do, my own business with about 13 staff at that time.
My view on this, is totally based on my own family, is that my Mother was struggling with her own issues, and nobody in my family was emotionally capable of dealing with the issues I faced. I chose to protect my family, especially my Mother, by keeping things as simple and as positive as I could. It worked, and fortunately I was cancer free at my last scan so I seem to be doing well.
I talked to my wife a lot, and the rest of the emotion that I felt overwhelmed with went into working, and exercising. In fact, exercise became, and still is, a solace to me.
I could get away from everyone else's emotions, fears, desires, wants etc, and just deal with things myself.
Perhaps your son is similar, but obviously only he can tell.
Perhaps he wants to protect you and look after his Mum.
Perhaps his work is solace, or perhaps it gives him some feeling of normalcy in a life that is no longer normal.
As others have mentioned us guys tend to bottle things up and hold on to the emotions a little. For me, treatment was tough but I had a plan, I had a target, the doctors told me what I needed to do. My wife helped improve my diet and really gave me a positive mindset but it was a lot harder for me after treatment when there was no safety net and an extremely high chance of recurrence.
Your son may need your help post treatment.
Please keep on letting us know how you go, and how your son goes.
