Just saw this on page 2 from @Phoenix1973
"I hate smears so much I have a double brandy before I go in. And I don't even like alcohol. I take it to get through that.
I was lucky as I was tested before the start age was 25.
They found pre-cancerous cells when I was 21. I had laser treatment and was fine physically. I've never been right mentally since."
I'm so sorry that's happened to you but the reason that the start age has now been raised to 25 is that women younger than that frequently have abnormal cells that will return to their normal state on their own. So the chances are that the treatment you had was unnecessary, and as you say, it's had a really bad effect on you mentally.
This is why Jo's trust ARE wrong to try to scare women into having smear tests by exaggerating the risks hugely. I've certainly e-mailed and tweeted them to tell them that. They are a single issue tiny charity beta.charitycommission.gov.uk/charity-details?regid=1133542&subid=0 with a talent for publicity. If you want proper accurate information on cervical cancer go to the Cancer Research website. Not Jo's trust.
I wouldn't mind Jo's trust if they gave factual, balanced, information, which is that cervical cancer is a cancer a woman has less than 1% lifetime risk of getting and that screening can reduce that risk, but we don't know by exactly how much. But instead, if you look at their twitter feed, it's full of stories about women who missed their smear and got cancer. The plural of anecdote is not data.
