@tinyitx been there, done that. Not over 40, but due to some health issues, I've had the displeasure of such an exam too. No shame in it at all, beats dying a horrible slow death of the cancer.
Let me reiterate to everyone else:
There's no shame in health. If you find a lump that's never been there, a sore that won't heal, a sore spot that won't settle, or anything that doesn't seem right, no matter the location, get it checked by a doctor. It could be the difference between a minor operation (i.e. a lump removed, like I had done two years ago), or permanent disability/ death.
We all hear horror health stories about issues that went unchecked for years because of stubbornness or desire to "save face" - don't be another statistic.
I learnt this lesson the hard way when I stubbornly ignored heart palpitations some years back. "It'll be fine" I said. I ended up watching myself flatline in an ambulance while being driven to hospital.
