I guess it is personal choice but to be honest if it were me, I'd rather have things checked out and find out that the diagnostic process was overzealous IYKWIM.
It is difficult if you have other issues but early detection DOES influence the course of action. It really bothers me when there are blanket statements that may stop people seeking advice, it really is misleading - some people have to fight for a diagnosis and more often than not they have to insist on further opinions/testing as they don't fit the 'mould'.
