Hello there.
i can understand your concern.
i do not know your father i'm sorry.
this is a benign thing and you can avoid it if you like, however, get it checked by a general surgeon in person once and take his opinion.
if he says, it should be removed then he will be able to remove it by surgery.
Best regards,
