Oh, I hear how scary this is...I've been there too with a sudden lump in my breast. Turns out that I develop benign cysts easily.

I did a quick search and found this:
"Symptoms usually do not appear until abnormal cervical cells become cancerous and invade nearby tissue. When this happens, the most common symptom is abnormal bleeding. Bleeding may start and stop between regular menstrual periods, or it may occur after sexual intercourse, douching or a pelvic exam. Menstrual bleeding may last longer and be heavier than usual. Bleeding after menopause also may be a symptom of cervical cancer. Increased vaginal discharge is another symptom of cervical cancer. "

Of course, I am no doctor, but from reading the symptoms it sounds different from what you have described.

I think you are doing the right thing in getting this checked out by a doctor right away. Let us know how it goes.
