I'm sorry for your diagnosis and hope you are surrounding yourself with good people through your journey.
As a doctor I will say that there is no real evidence of this decline in age of first cancer.
I respectfully suggest that you may have bias through the inevitable path your life has now taken, the people you talk to, see through your treatment etc.
An aside to this is that we are much better at detecting breast ca, prostate ca and cervical ca through screening which leads to earlier detection (and earlier staging, meaning higher survival)
