Is CIN 2 precancerous?

CIN – The outer surface of the cervix is composed of cells called squamous cells. A precancerous lesion affecting these cells is called CIN. These changes are categorized as being mild (CIN 1) or moderate to severe (CIN 2 or 3).

How long does it take for CIN 2 to develop into cancer?

However, it is estimated that 5% of CIN 2 and 12% of CIN 3 cases will progress to invasive cancer if untreated. In general, it takes 10 to 20 years for CIN to progress to cancer, allowing a significant time period for detection and treatment. Progression from CIN to cancer requires persistent HPV infection.

Should CIN 2 be treated?

Right now, CIN2 is typically treated. But some studies have suggested that CIN2 lesions often regress completely without treatment and should therefore be simply monitored instead.

Should I worry about CIN 2?

CIN 2. CIN 2 means two-thirds of the thickness of the cervical surface layer is affected by abnormal cells. There is a higher risk the abnormal cells will develop into cervical cancer.

Is CIN a precancerous lesion?

What is cervical dysplasia? Cervical dysplasia is a precancerous condition in which abnormal cells grow on the surface of your cervix. The cervix is the opening to your uterus that's attached to the top portion of your vagina. Another name for cervical dysplasia is cervical intraepithelial neoplasia, or CIN.

What is CIN

What type of HPV causes CIN 2?

Results: HPV was detected in 92.9% of women with CIN 2-3 and high-risk HPV (HR-HPV) was detected in 85.8% of them. In women with cervical cancer, HPV was positive in 96.5%, HR-HPV detected in 93%.

What is CIN 2 colposcopy?

Listen to pronunciation. Moderately abnormal cells are found on the surface of the cervix. CIN 2 is usually caused by certain types of human papillomavirus (HPV) and is found when a cervical biopsy is done. CIN 2 is not cancer, but may become cancer and spread to nearby normal tissue if not treated.

Can CIN 2 come back after LEEP?

About 23% of patients develop CIN2+ after LEEP treatment due to residual or recurrent lesions. The majority of patients with HPV infection were HPV negative before treatment, but 16,4% were still HPV 16 positive after treatment, indicating that conization do not necessarily clear HPV infection rapidly.

How long does it take for CIN 2 to regress?

Conclusion: CIN2 lesions regress without treatment in one year, although an ablative procedure is more effective.

How often does CIN 2 come back?

The reason for conization was CIN2 in 32.7% of patients and CIN3 in 66.9% of patients. Overall, 175 women received a second conization within the first 5 years after primary treatment, for a recurrence rate of 6%.

What is the best treatment for CIN 2?

laser or loop electrosurgical excision procedure (leeP) are the preferred treatment methods for recurrent CIN 2 and CIN 3 (sor: B, based on clinical trials without randomization).

Does HPV always cause CIN 2?

One explanation for the lower rate of progression of CIN 2 compared with CIN 3 is that CIN 2 is more likely to be caused by oncogenic HPV subtypes 31, 33, 35, 39, 45, 51, 52, and 58, which have a weaker association with development of cancer than the more highly oncogenic subtypes HPV 16 and 18, which are commonly ...

Can precancerous cells come back after LEEP?

LEEP works very well to treat abnormal cell changes on the cervix. If all of the abnormal tissue is removed, you won't need more surgery. In some studies, doctors were able to remove all the abnormal cells in almost every case. But abnormal cells may come back in the future.

Should I get a hysterectomy if I have precancerous cells?

If the precancerous disease is more extensive or involves adenocarcinoma in situ (AIS), and the woman has completed childbearing, a total hysterectomy may be recommended. 1 During a total hysterectomy, the entire uterus (including the cervix) is removed.

How serious are precancerous cells?

Often, precancerous lesions are not invasive and a person will not develop cancer. In some cases these precancerous cells, if left alone, may go on to become “invasive” cancer cells. Sometimes, it may take these cells a few years, or even decades to progress.

How long does it take HPV to turn into throat cancer?

Cancer can appear decades after exposure

Most people may get a throat infection from the virus that goes away, but some people may go on to develop cancer in the throat or tonsils some 20 to 30 years later.

Can CIN 2 heal itself?

CIN 2 lesions often clear up on their own, but can also progress to CIN 3 lesions. CIN 3 is the most severe. It's a very slow-growing disease, though: fewer than half of CIN 3 lesions will have become cancer within 30 years.

What happens if CIN 2 is left untreated?

High-Grade Abnormalities CIN-2 & CIN-3

These cells are more likely to become cancerous and invade deeper layers of the cervix if left untreated. If high-grade abnormalities are detected on a Pap smear, the woman is advised to have a colposcopy and biopsy.

Why do I need a second LEEP procedure?

In some instances, you may need a repeat procedure to remove all the cells completely. You may also need an additional LEEP if abnormal cells return. You're at a greater risk of recurrence if you're infected with a high-risk strain of the human papillomavirus, or HPV.

Do I still have HPV after a LEEP?

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.

How many times can you do a LEEP procedure?

If the margins are positive, you may need a repeat procedure. In addition, six months following a LEEP, you'll have a follow-up appointment that includes Pap and HPV tests. In some cases, abnormal cells are found again. If this happens, you may require another LEEP.

How do they remove precancerous cells from the cervix?

Also called loop electrosurgical excision procedure (LEEP), this is the most common way of treating precancerous changes of the cervix. The abnormal tissue is removed using a thin wire loop that is heated electrically. The aim is to remove all the abnormal cells from the surface of the cervix.

Is CGIN worse than CIN?

CGIN is usually classified as low grade (mild) or high grade (severe). High grade CGIN is the equivalent of CIN3. CGIN can be multi-focal – this means that more than one area is affected at one time, with normal tissue lying between them.

What causes precancerous cells in cervix?

Infection with the human papillomavirus (HPV) is the main risk factor for precancerous changes in the cervix. Smoking and having a weakened immune system increase the chance that an HPV infection will not go away on its own and will develop into a precancerous condition of the cervix.

Does removing the cervix get rid of HPV?

Surgically treating genital warts doesn't cure a human papillomavirus (HPV) infection, however, and warts can return after surgery if the immune system does not eliminate the infection. Surgery may be used to treat moderate to severe cervical dysplasia by removing abnormal cells on the cervix.
