Glandular neoplasia can i have 3rd LLEZ

Hi I have just been referred to MDT after 6 month smear following 2 LLEZ for glandular neoplasia. I had my smear at the colposcopist, and she couldn’t see abnormalities, but the smear has come back with high grade changes. Has anyone had any similar experiences. I figure they probably will consider a hysterectomy l, but has anyone had a 3rd LLEZ? TIA
