Yes, be diligent, but don't let that build to paranoia. Be informed by the doctors not the internet (including us). We're not doctors we are mostly patients and carers. We'll share our experiences and suggestions with the best intentions, but you should take everything that concerns you to your doctor.

I use the internet to understand why the doctors are doing/saying what they do. If they say don't worry about it for 3 months because of xyz, I try to put it aside for 3 months. don't worry about it. The worry never quite goes away, but if I can't put it on a shelf for a while it would drive me nuts.
