Abortion dysplasia. Abortion is not related to cervical dysplasia, but having multiple sexual partners or a partner with a sexually transmitted disease are. Any pregnancy means the woman's partner didn't use a condom and would explain the risk of dysplasia.
No. There is no evidence to show that abortion causes or worsens cervical dysplasia. Most dysplasia is caused by the human papilloma virus (hpv), which is a sexually-transmitted virus.
