Hi, I'm just getting over a bladder cancer diagnosis from March. I found a 4mm 'slightly darker than skin coloured' (not black) lump/nodule/wart on my breast and my doctor looked at it, with a lens, not sure if it was a dermascope. He said that he isn't concerned as it looks like a wart but because of my history and its just appeared he cant rule out melanoma. He has urgently referred me to dermatology. It bled last night but has 'dried up' now and left a dark type mark(scab?) How often do warts in unusual places end up to be melanoma. Also would a melanoma 'usually' bleed and then stop bleeding/heal Thank you
