Come to a support event to meet other people who have had a cervical cancer diagnosis.
Your colposcopy results may show cell changes (abnormal cells) on your cervix. Your results letter usually calls these:
Finding out you have cell changes may be worrying, especially if you haven’t heard of CIN or CGIN before. Try to remember that cell changes are not cervical cancer and having them does not mean you will develop cervical cancer. Most cell changes will get better by themselves or with treatment.
On this page, we talk through the differences between CIN and CGIN, and try to explain some of the words you might read or hear. We hope it helps you feel more reassured, but if you need some extra support, our support services may be able to help.
It is important to know that CIN and CGIN are not cervical cancer.
CIN and CGIN are named for the part of the cervix they affect:
CIN is graded from 1 to 3. The number shows how deep the cell changes go into the outer surface of the cervix. Sometimes, the terms low grade or high grade are also used.
One-third of the thickness of the outer surface is affected.
It is unlikely these cell changes will develop into cervical cancer. They will probably go back to normal by themselves. You do not need treatment and will be invited for cervical screening (a smear test) in 12 months to check the cell changes are gone.
Two-thirds of the thickness of the outer surface is affected.
There is a higher chance these cell changes may develop into cervical cancer. Depending on your situation, you may be offered:
You can discuss options and your preference with your colposcopist.
The full thickness of the outer surface of the cervix is affected.
If not treated, it is more likely these cell changes will eventually develop into cervical cancer, so you will be offered treatment to stop that happening.
CGIN is usually described as:
If you have any grade of CGIN, you will be offered treatment.
Most cell changes do not develop into cervical cancer. Once cell changes are found and graded, colposcopists can monitor or treat them as needed.
If CIN is not monitored or treated, it may develop into squamous cell cervical cancer. This type of cervical cancer is named after the squamous cells on the outer surface of the cervix.
If CGIN is not treated, it may develop into adenocarcinoma. This type of cervical cancer affects the glandular cells up inside the cervical canal.
If you are really worried or have specific questions, ask your colposcopist to talk you through your individual situation. They can give support and may be able to reassure you.
The most important thing to remember is that CIN and CGIN are not cervical cancer and that you will have a team of dedicated experts caring for you.
