I had CINII/moderate dysplasia. I am from the US, although now married to a Scotsman and a naturalised British citizen.
I had TWELVE normal smear tests, as yes, women are screened yearly in the States.
At age 30, however, I had developed CINII in one year.
I am so glad they don't do every three years there. I may have gone on to have cancer by then!
I, too, had a laser procedure.
I have insisted on being screened EVERY YEAR SINCE and I don't care if I have to pay for it myself.
I volunteered my biopsy sample, done at the time of my colposcopy, to medical research for the vaccine, and I know I have HPV.
Most of the time, a person can live w/this and never had any abnormal smears.
But no one knows why, in some people, it goes on to dysplasia or worse - although it is known that smoking can increase the risk.
Until then, I'm going to insist on yearly smears and encourage both my daughters to be vaccinated when the time comes.
Smear tests are cheap and save lives.
