Is CIN 2 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.

What is cin1 and CIN 2?

Low-grade neoplasia (CIN 1) refers to dysplasia that involves about one-third of the thickness of the epithelium. CIN 2 refers to abnormal changes in about one-third to two-thirds of the epithelial layer. CIN 3 (the most severe form) describes a condition that affects more than two-thirds of the epithelium.

How quickly does cin3 turn 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.

What is high-grade squamous intraepithelial lesion CIN 2?

HSIL ~ High-grade squamous intraepithelial lesion This diagnosis means the cells appear very different from normal cells. These precancerous lesions are more severe than with LSIL, but involve cells on the surface of the cervix. They may also be called moderate or severe dysplasia, or CIN 2 or 3.

Can precancerous cells come back after LEEP?

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.

What if your 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.

How serious is CIN3?

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. “But we have no way to determine which women with CIN 3 will progress to cancer and which women will not.

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.

How serious is HSIL?

High-Grade Squamous Intraepithelial Lesions (HSIL) means that there are moderately or severely abnormal cervical cells that could become cancer in the future if not treated. Your health care provider will likely ask you to come back for a colposcopy.
