Hi everyone :)

I am a 20 year old university student and in September 2021 I had a mole removed from my face. I was very worried at the time and anxiously waited the biopsy results. A few months passed and I hadn't heard anything and so I rang the hospital and they informed me they didn't have my results yet. They didn't seem worried and because I was so busy with uni I sort of just forgot about it, assuming everything was fine and thinking if something was wrong I would have been contacted. 
 

I received a letter today (5 months post removal) telling me my mole had been sent to three different hospitals as there was concern over the mole. I was informed that the mole is benign but I will have to go in for a a 'little further surgery' on the 14th of February. The letter provides no details as to why I need this surgery or what the procedure involves so I was just wondering if anyone has any advice as to what this could be? 

I have looked online and the cancer research website says if a biopsy is clear and no cancerous cells are found then no further action is required so i'm worried as to why I need this second procedure if the mole was benign? 

I've tried calling the number on the letter but I can't get in touch with anyone and I just keep getting out through to the skin cancer helpline to leave a message. 

Any reassurance would be great as I'm already stressed enough with exams etc and this situation really isn't helping!
