Following your recent visit to the Colposcopy Clinic, the findings suggest there are some mildly abnormal cell changes to your cervix which are known as CIN1, (Cervical Intraepithelial Neoplasia, Grade 1).
What is the significance of CIN1?
CIN1 is also defined as a low grade abnormality of the cervix,
where the cells are considered to have developed into a minor
This condition is usually kept under close surveillance. National Guidelines for the management of CIN1 by treatment or surveillance are based on research evidence showing that one out of every two of these low grade abnormalities are self-limiting. This means that, given time, CIN1 will return to normal without active treatment.
CIN is a pre-cancerous condition that can be subdivided into three
grades: CIN1, CIN2 and CIN3. These grades can then be
categorised into high risk (CIN2 and CIN3) and low risk (CIN1).
It is important to remember that all CIN does not develop into cancer, and that treating all grades of CIN would lead to overtreatment for many women.
Current data suggests that less than 1 in 100 of CIN1 patients go on to develop cervical cancer. Although it is not possible to predict at the outset the potential outcome for individual women, we do know that CIN1 has a tendency to return to normal in a significant number of women1,2.
Based on such evidence, the National Guidelines state that CIN1 may either be treated or kept under close observation.
What does the management of low-grade abnormalities by surveillance involve?
You have been offered a conservative management option for a low-grade abnormality of the cervix in the hope that the cells will return to normal without active treatment.
Conservative management of low-grade abnormalities is completely safe. However, since this involves close observation until the cervical screening tests return to normal, it is important that you keep your appointments.
If CIN1 is diagnosed, you will be discharged from the colposcopy service back to your GP for a further screening test in 12 months. Further follow up will be determined by that screening test result.
Although low-grade abnormalities can be managed indefinitely by surveillance, this may change if it does not progress. Our local policy is to suggest treatment if the abnormalities are still persisting after a period of two years, or to treat immediately if the abnormality progresses in grade or size.
What if I can’t attend an appointment?
It is very important that you attend the Colposcopy Clinic when an appointment is made for you.
If you cannot attend for any reason, please let us know so the appointment can be used by someone else and we can arrange another appointment for you.
If you are unable to attend a clinic and wish to change your appointment, please contact our clerical staff:
