When they do the leep surgery the doctor attempts to remove all of the cancerous cells from your cervix. If for any reason some were missed then more cancerous cells can appear and the surgery my have to be done again. But there is hope, if you have to go through the surgery again, at least it was caught early enough and it can be taken care of. You will always have that particular HPV strain in your body, but your bodies immune system will learn to fight it off so it would become cancerous. You will be okay, just keep having your yearly paps. Also your paps many come up abnormal for a while after the surgery, it takes a while sometimes. Good luck, you'll be alright.
