Early review - confused !

Can anyone offer any advice ? Had a lletz treatment which came back as CIN . Did not mention grade . It said in brackets not cancer . Which is Obv great , however they want to review this again in 2 months so have a date to go back in cple weeks . I was led to believe I wld be reviewed after 6 mths. Why so quick ? Any ideas ? 

Maybe the didn't get clear margins on the lletz.. If that's the case they are giving you a chance to heal if the need to do another lletz x
