Q&yourA: LEEP procedure for pre-cancerous cells of the cervix

I got an email from someone who wishes to remain anonymous. She's in her early 30s and doesn't have any children yet but is hoping to have some in the next few years. Her doctor has discovered precancerous cells on her cervix and has scheduled her for the LEEP procedure to remove the precancerous tissue. She's afraid that this will hurt her cervix and affect her ability to carry a pregnancy.

Can anyone share experience either with precancerous cervix diagnosis, the LEEP procedure, or fertility issues after a LEEP procedure? And, of course, with dealing with having precancerous cells inside her body?
