A colposcopy is a simple procedure used to look at the cervix, the lower part of the womb at the top of the vagina. It's often done if cervical screening finds abnormal cells in your cervix.
These cells aren't harmful and often go away on their own, but sometimes there's a risk they could eventually turn into cervical cancer if not treated.
A colposcopy can confirm whether cells in your cervix are abnormal and determine whether you need treatment to remove them.
You may be referred for a colposcopy within a few weeks of cervical screening if:
A colposcopy can also be used to find out the cause of problems such as unusual vaginal bleeding (for example, bleeding after sex).
Try not to worry if you've been referred for a colposcopy. It's very unlikely you have cancer and any abnormal cells won't get worse while you're waiting for your appointment.
A colposcopy is usually carried out in a hospital clinic. It takes about 15-20 minutes and you can go home the same day.
If it's obvious that you have abnormal cells in your cervix, you may have treatment to remove the cells immediately. If this isn't clear, you'll need to wait until you get your biopsy results.

It's often possible to tell you right away if there are any abnormal cells in your cervix. But if you had a biopsy, it may take up to 2 to 4weeks to get your results in the post.
The result of your colposcopy and/or biopsy will be either:
Your doctor or nurse may use the term CIN or CGIN when discussing your biopsy result. This is this medical name for abnormal cells.
It's followed by a number (for example, CIN 1,2 or 3) that indicates the chances of the cells becoming cancerous. A higher number means a higher risk of cancer developing if the cells aren't removed.
Treatment to remove abnormal cells is recommended if there's a moderate or high chance of the cells becoming cancerous if left untreated.
There are simple and effective treatments that can be used to remove the abnormal cells, including:
LLETZ and Cold coagulation treatments are usually carried out while you're awake but your cervix is numb in the treatment called LLETZ.
