I have a question umm about like a year ago?

i got a tattoo on my finger its on the ring finger of my right hand its of a normal bow its black outlines and pink reddish shaded. i got it done by hand like without a gun just ink and a professional steralized needle, and its almost faded and i was wondering could i be a doctor even though i have that tattoo there? because one of my friends said i would have to cover it because its not healed or something like that even if yoyu've had it for years so im not sure if it will affect my career?
