It is very unlikely to be cancer, I've gone through the whole process of getting a colposcopy several times. The Pap smears you had showed some abnormal cell types, so now instead of a little scraping they want to go in with a little camera to see things better. My first time I had a "moderate" concern for cell abnormality, so they took a small biopsy it pinched a little and bled like a period for s day or two. I had to go back several times over several years and each time it appeared as if my body was getting rid of the abnormal cells on its own. My coworker told me she had a procedure done to get rid of a few deeper layers over her cervix (ablation) as her body didn't clear it like mine. And she's since had kids no problem and no more abnormal pap screens. No need to be concerned, they are just doing more tests just to be absolutely sure and catch it early if it is abnormal. Good for you for getting pap screen it's important to take care of your health
Very interesting, thank you!
