I Have A Discoloration Under The Nail Of My Right
Not something serious
Hello and welcome to 'Ask A Doctor' service.
I have gone through your query and reviewed the images.
It is most likely a nail bed nevus. It does not look like cancer- well defined, small in size, uniformly colored. I advise you to not worry about it.
Hope I have answered your query.
Let me know if you need any more assistance
Regarding a nevus
A nevus is like a mole anywhere else on body. Chances of a cancer arisiing from a nevus are minimal and similar to what they are from a mole anywhere else on body. Cancer arising from a nevus (melanoma) at nail would present as an large, irregular area of pigmentation, sometimes also with ulceration and breakage of the nail plate.
