###Human: Observed few changes in a mole. Is it something alarming? ###Assistant: Hi. If there is a change in color, size, margin and shape in a pre-existing mole, especially in this age, then it is always an alarming sign.  As you said it is changing its texture and color, then yes definitely. We should suspect about melanoma. In your case it is very difficult to say either it is a just normal change in a mole or precancerous change. For further information consult a dermatologist online -->
