I think it is obvious the combination of self-induced stress and HPV are what's causing the issue. That this is a direct sign of cervical cancer I think would be a stretch, not to mention nearly impossible to draw a conclusion on over the internet. The only way to know is to go through with your exam. In the meantime, take heart in the fact at that 90% of HPV can be cleared by the body (on it's own) within 2 years (and even faster by leading a healthy lifestyle). It's good you have questions and I would encourage you to write them down and take them with you to your appointment. The doc will appreciate this and it will be more productive for both of you and keep the appointment on track. Write down the doc's comments and suggested reading (which he or she will probably give). Best of luck.
