Metaplastic changes??

Hi all. Im 29. Had an abnormal pap on 7/28/17 cam back as acus and high risk hpv. Had a colposcopy last wednesday and got my results yesterday...i have cin3 at my 12 oclock area inside and out..but did anyone get anything about metaplastic changes on thier pathology reports for colposcopy biopsies.  It says for endocervix and curretage. Fragments of benign endocervical tissues with metaplastic changes..all ive seen on google is that its meteplasia and could potentially turn in to cancer..does this mean i need to get that part removed too? Im so confused with this report.  And the doctor didnt explain much to me. Going in on  the 14th for my leep procedure.
