If you have double high risk hpv and abnormal cells for 2 yrs straight what are the chances of having cervical cancer?

Cervical cancer??: The most common strain of HPV which can transform the cells of your cervix to become cancerous is Type 16. There are other Types of HPV which can do that and perhaps that is what you mean by double high risk. Nevertheless infection does not mean those viruses have performed their nasty deeds yet. You would first get a "Pap" smear done and if + then have a colposcopy to remove those nasty cells.
