Sue1 - what is the worst that could happen? Many cancers can be surgically removed and with appropriate follow-up treatments will be gone. Many people 'live with' rather than 'die of' cancers dependant on which has been diagnosed. At a late age breast disease is usually slow growing so women live with it rather than opting for intervention.
Is there a history in your family regarding chronic illness?
My worry when diagnosed in 1995 was that panic attacks would take over so that I would not be able to attend my appts and radiation sessions. Adrenaline saw me through.
Fear can be all controlling. I have a phobia ......... since age 3 and it overwhelms me at times

. Logic flies out the window, fast
