Is CIN a cancer?

Is CIN the same as cancer?

CIN is not cancer. But if the abnormal cells are not treated, over time they may develop into cancer of the cervix (cervical cancer). CIN does not cause any symptoms. You are not likely to find out you have it unless you have cervical screening.

What percentage of CIN 1 turns into cancer?

Approximately 60% of CIN 1 lesions regress without treatment and less than 1% progress to cancer. However, it is estimated that 5% of CIN 2 and 12% of CIN 3 cases will progress to invasive cancer if untreated.

Is high grade CIN a cancer?

CIN 2 is not cancer, but may become cancer and spread to nearby normal tissue if not treated. Treatment for CIN 2 may include cryotherapy, laser therapy, loop electrosurgical procedure (LEEP), or cone biopsy to remove or destroy the abnormal tissue. CIN 2 is sometimes called high-grade or moderate dysplasia.

Can CIN1 progress to cancer?

The risk of developing cancer is related to the grade of CIN. We know that most cases of CIN1 will go back to normal without any treatment. The risk of CIN1 developing into cancer is very small. However we know that CIN2 and CIN3 may develop into cancer in some cases, if left untreated.

What if cervical biopsy is positive?

Results of a cervical biopsy

A positive test means that cancer or precancerous cells have been found and treatment may be needed.

What is Stage 3 cervical dysplasia?

CIN 3 is not cancer, but may become cancer and spread to nearby normal tissue if not treated. Treatment for CIN 3 may include cryotherapy, laser therapy, loop electrosurgical procedure (LEEP), or cone biopsy to remove or destroy the abnormal tissue. CIN 3 is sometimes called high-grade or severe dysplasia.

What happens if CIN 3 is left untreated?

It is dangerous to leave CIN-2 and CIN-3 untreated. If, over a long period, the abnormal cells spread deeper into the cervix or to other tissues or organs, the disease is called cervical cancer and will require more aggressive treatment. High-grade lesions (CIN-3) usually take many years to develop into cancer.

Do you still have HPV after LEEP procedure?

Although LEEP does not completely eradicate HPV infection, our results indicate that most HR-HPV infections are cleared after LEEP with negative margins. The clearance rate is increasing gradually after surgery. Our persistence rate was 40.9 % at 6 months, 20 % at 12 months and 11.8 % at 18 months.

Can high grade dysplasia go away on its own?

Cervical dysplasia can range from mild to severe, depending on the appearance of the abnormal cells. On the Pap test report, this will be reported as a low- or high-grade squamous intraepithelial lesion (SIL) or sometimes as atypical squamous or glandular cells. Dysplasia could go away on its own.

How long does it take for abnormal cells to turn into cancer?

These aren’t cancer cells, but cells that may turn cancerous if left untreated for many years. It takes 10-15 years for pre-cancer to progress to cancer.

How many times can you have a LEEP procedure?

Though this condition can happen, it does not put a limit on how many times LEEP can be performed. If a woman has CIN, the LEEP needs to be done when recommended based on factors unrelated to the potential repetitions of the procedure.
