if you're annual includes a pelvic/pap and breast exam........... please done skip it. Bad things can happen really fast and missing a yearly exam can be the difference between preventive maintenance - and things more drastic and invasive. I speak from experience.
In 2000 I was going to skip my annual well woman exam. Something told me I should go ahead and have it done. While doing the vaginal exam the doctor says, "oh wow........ I have never seen anything grow this fast - you're last exam was totally normal!" When I asked her what it was she told me I had white spots all over my cervix. She rushed a biopsy and I had SEVERE cervical dysplasia - had I missed that yearly exam I would most likely not be sitting here cautioning you to not skip yours. She told me had I waited another year for my exam I would probably be at stage 4 cervical cancer. I had to have a cone biopsy to remove all the pre-cancerous cells. I have been fine since.
Don't mess around with that stuff. Teeth cleaning can wait........ in fact buy Rembrandt whitening tooth paste and you won't need cleanings - it takes off all the tartar. But yearly exam and mammograms are not something to poo-poo off. If you haven't had a mammogram yet - you should think about having a baseline done soon.
That's my 2 cents!
