Hello

i had a mole which had grown and the boarder had gone almost blurred and different colours.

I was put on a two week referral to a consultant, to have it checked and I was such a state of anxiety. 

I went today and the first consultant said he wasn't sure if it was ok or not, after examining it, so said he would get his colleague for a second option. His colleague then said it was fine, but looked again and said let's take photos and review again 3 - 6 months, to see if it's Changed again and then sent me on my way.

I have some trust issues along with health anxiety, so I know I over think every situation and it's someting I am trying to work on, but I wondered if anyone else had been given the watch/monitor approach, rather than just to remove it and send off for histology please? 
 
I am unsure if a mole can change and still be benign, despite its boarders and colour changing :( I'm guessing it can, but trying to stay away from Google :) 

Thank  you
