Having a Pap smear that showed precancerous cells is a certain risk factor to undergo a Pap smear annually, as in your cases. Having a larger area of precancerous cells is a indication to have Pap smear earlier, because sometimes it takes shorter period than a year for precancerous cells to develop into cancerous.
This does not mean you have cervical cancer. It means that some of the cells were abnormal and that if they were left untreated, they could go on to develop into cervical cancer.
What was the exact diagnosis from the biopsy?
Is the lesion identified as low-grade or high-grade squamous intraepithelial lesion?
