Moderate cervical lesions — formally known as cervical intra-epithelial neoplasia grade 2 (CIN2) — are abnormal cells on the surface of the cervix.
CIN is not cervical cancer but does have the potential to progress to cancer. However, in many cases, therefore these cells may also return to normal or remain unchanged.
Right now, CIN2 is typically treated. But some studies have suggested that CIN2 lesions often regress completely without treatment, therefore, be simply monitored instead.
Some experts feel that approach could be especially important for younger women, since treating these lesions can pose a risk to future pregnancies.
However, in women younger than 30, the rate of regression rose to 60 percent, the researchers noted, while the rate of persistence was 23 percent, and the rate of progression was 11 percent.
