Colposcopy results back as cin2!!!worried!!

Hi everyone! Wondered if anyone could help me. I read the forums on here all the time but have never joined. First time for everything! I recently had my first smear and the results came back as abnormal cells. I then went for a biopsy and I got my results back today. The letter explains I have low grade abnormality cin1 and moderate grade abnormality cin2 and I have to go for treatment in 6 months time. I am really worried. What is the treatment. Will the cells change???? Thanks :) 

If the cells haven't cleaered within those 6 months, the most common treatment is lletz to remove the abnormal cells
