If i have cervical dysplasia, could it definitely progress to cancer?

Yes: It definitely could progress to cancer. Fortunately, it usually doesn't. Nonetheless, because it could, it is imperative that you be followed with repeat paps and biopsies until it goes away or that you be treated to make it go away (and then be followed to make sure it has).

Usually No: Most commonly the dysplasia will resolve on ts own, not, in fact, progress to cancer. The greater the level of dysplasia (graded i, ii, or iii) the more likely it will progress but even the most advanced dysplasia may not become cancer. Not smoking and taking Folic Acid regularly may help your body to eradicate the dysplasia naturally. But don't avoid seeing the doctor!
