How to tell my parents that i need biopsy to inspect my bump at my lip with a black dot at the center? how to tell them? im horrified. how?

That's odd....: If a person talks with his parents on a usual, normal basis, then there is nothing special about telling them about a bump that needs a biopsy. It is done the same way that any normal, everyday conversation is done. However, which doctor says the bump needs a biopsy? On the face, a specialized dermatologic surgeon or plastic surgeon can give an opinion. Presumably, it's not just a blackhead.
