Snooki said she’d been dealing with abnormal Pap smears for years, but stayed on top of her screenings -- and urged fans to do the same, stressing Pap tests can detect abnormal cells before they turn cancerous.

She revealed her next step is a PET scan, and said she’ll likely undergo a hysterectomy instead of chemotherapy.

Despite the frightening diagnosis, Snooki ended on a hopeful note -- encouraging others going through similar battles to speak up and lean on support.
