Mentions of "the Bethesda system" without further specification usually refer to the cervical system, unless the thyroid context of a discussion is implicit. 161:
CIN 1 is the most common and most benign form of cervical intraepithelial neoplasia and usually resolves spontaneously within two years. Because of this, LSIL results can be managed with a simple "watch and wait" philosophy. However, because there is a 12–16% chance of progression to more severe

HSIL does not mean that cancer is present. Of all women with HSIL results, 2% or less have invasive cervical cancer at that time, however about 20% would progress to having invasive cervical cancer without treatment. To combat this progression, HSIL is usually followed by an immediate
