First, a bit of background.
I first started getting smear tests when I was 17 after some abnormal bleeding after sex. I have them most years, though I've moved a lot and so I missed a few. I always get abnormal results, and once when I was younger I was referred to colposcopy and had a punch biopsy, which from memory came back fine.
I am now nearing my 31st birthday. I have had another abnormal smear in Sept, but this is the first time since I was younger that I've been referred back to colposcopy. They did another biopsy which showed CIN3, and a month later I've just had the Lletz procedure.
The doctor showed me the sample, which looked to me to be most of an inch in size.
My question is - is it possible for cancer to show when testing the Lletz sample if it didn't show in the biopsy? Or am I worrying over nothing?
