I had to go to hospital in october last year after getting abnormal results. I had been getting mild results for a number of years always followed by a normal result on my follow up smear. My last two smears went from mild to moderate abnormal results which is why they had me in. I was pretty worried about it but the doctor at the hospital told me it was routine practice to get you in and sort it out asap. I had laser treatment and a biopsy done which showed the cells were pre-cancerous but thankfully the results from it also said 'full excision of cells'
The procedure didnt hurt at all, the staff were fantastic and apart from a slight bit of aching for the rest of that day I wouldnt have known I had had it done.
I hope you mate gets on okay, please tell her to try not to worry :)
