Colposcopy & biopsy 1111

Hi ladies
I had lletz treatment & biopsy done just over two weeks ago. Today i recieved a letter from my consultant who done the treatment.
It says the following: colposcopy examination was adequate and revealed normal vaginal epithelium. On the cervix the squamocolumnar junction was visualised in its all entirety. There was high density acetowhite changes with some mosaic pattern noticed.
What does this mean?
Is this good or bad? Has any one else had simular thing to this?

If they want to see you again did they pit that in theetter and phone your doctors they mist have a copy if not email them one over so they can explain to you
