Hi S.,
Abnormal cells can be something other than cervical cancer.
Did they test you for HPV? That is the next thing I would have done. Determine if you have contracted a strain of the virus for which you weren't vaccinated.
How old are you? How old were you when you were vaccinated? Had you been sexually active BEFORE getting vaccinated? Had you engaged in ANY oral sexual activity (or even touching that involved "fluids" of either of you) before getting vaccinated? Is it possible that you had already contracted HPV prior to the vaccine? or, like I said above... that you have contracted a 'different' strain of HPV?
The HPV vaccine only protects against 2-4 of the most common strains. So, you can still get an HPV strain that you weren't vaccinated for..... think of the Flu vaccine. The flu vaccine only vaccinates you against the most popular strain..... but you can get another strain of the flu if you happen to run across someone who has a different strain. Getting the HPV vaccine does not mean you can have unprotected sex and you'll never contract HPV.
Also - there are other things that can cause cervical cancer. it's not a converse relationship (HPV causes cancer, but cancer is only caused by HPV). Instead it's that these identified strains of HPV have been known to cause cervical cancer. But you can get cervical cancer (or throat cancer etc) and NOT have HPV.
But it doesn't sound like you have cancer, right?
You just have an abnormal pap. And I'm not minimizing that..... yes, that is very scary. But they're having you come back in 6 months..... not next month so it means they want to watch the cells. They aren't doing a biopsy, right? They're just going to do another pap.
So, take a breath and try not to worry too much until you go back to your Dr.
Good Luck.
