In your case, your mole has recently become bigger, and you may often encounter it on your lips. In principle, it should be removed.

But considering your age, on the one hand, there are certain risks in surgery and anesthesia when you are old, and on the other hand, it will take some time for the malignant transformation of the mole, so if there are no symptoms at present, it is not necessarily meaningful to actively remove it. You can discuss it with your family again.
