I had this mole on my chest checked last year by a doctor and she wasn't interested in the slightest. Said it had a clear border and we can develop new moles until we're around 40 (I'm 35).
This mole appeared when I was around 30 years old. Started off darker (it still was when I saw the dr last year) but I've noticed that it has become a lot lighter this summer. Is it worth ringing up the GP again? I'm worried it will be wasting their time. For reference it is 5mm diameter.
