Dear newmommy,
Excuse me in advance for my bad English, I am a foreigner but I will try to explain you as simple as possible since I am not aware of the medical terms in English.
As you know the HPV is a sexually transmitted vyrus and lots of sexually active women carry it. Do not get me wrong, it is not a sexually transmitted desease such as syphilis for example, it is just a vyrus and recently the scientists discovered that the cancer of the uterus is caused exactly by HPV.
The colposcopy is a test by which your doctor will smear the upper part of your uterus with a special preparation. If the HPV has injured your uterus this preparation will make the injured area to turn to a different color. After smearing the doctor will observe with a microscope. It is not painful at all so there is nothing to worry about. The feeling is like taking sample from the vaginal secretion and takes no more than 10 minutes.
If there`s no any injury probably your doctor will perscribe you an antibiotic to kill the HPV. If there is an injured area the doctor have to "burn" it with another preparation in order to stop the vyrus from penetrating ahead. It is not painful too.
Do not put off your colposcopy, I have been through it, I was also scared, especially after reading in Wikipedia that the colposcopy is a very painful test and didn`t believe the contary when asking my doctor. I had also HPV, as long as I remember in stage 1. After the coposcopy my doctor perscribed me an antibiotic and the second test after a month was negative.
I spoke to my GYN about the HPV since it is a relatively new founed condition. She explained me that the science still does not know how did it appear, it is transmitted sexually and leads to an uterus cancer ONLY if not treated in time. She also told me that there is a statistic prooving that a big percentage of the women (obviously men too) carry it, but according her the percentage is even bigger, sth like 90%. There is a vaccine against it but unfortunately it is not good for us, only for young girls before having their first sexual contact.
I wish you the best of luck and assure you that there`s nothing to be afraid of!
