Hi T.---Try not to worry too much. Most abnormal smears are actually the result of false positives, not that there are any abnormal cells.
I had an abnormal pap MANY years ago, and have never had another.
Just to help ease your nerves, worldwide, cervical cancer affects 16 of every 100,000 women. That is a very low rate of disease. So, don't worry, because even if it ever happened, it is one of the easiest to detect and treat. And know your risk factors. The biggest risk for contracting cervical cancer is multiple sex partners, which increase the risk of acquiring the HPV virus.
Eat a healthy diet, consisting of MOSTLY fresh fruits and veggies, whole grains, legumes, nuts and seeds. This diet will keep your immune system strong, able to fight those pesky viruses before they can cause any trouble. Let me know if you would like any additional info on an optimal diet, I am honored to help. I am taking a series of wellness classes, taught by a naturopath who has her PhD in Nutrition. I have lots of info to share.
Good luck. D.
