What is the difference between CIN 3 and carcinoma in situ?

Is CIN3 considered cancer?

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.

Are CIS and CIN3 the same?

Cervical Histology

The latter includes carcinoma in situ (CIS), a preinvasive carcinomatous change of the cervix. The term CIN2+ is used to indicate CIN2 or worse (CIN2, CIN3, or cancer), and CIN3+ is used to indicate CIN3 or worse (CIN3 or cancer).

How fast does CIN3 turn cancerous?

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 percentage of CIN 3 turns 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.

Can CIN3 be cured?

Thermal coagulation appears to cure most CIN 3 cases, and the time needed for the treatment is a fraction of that required for cryotherapy.

Can you get CIN3 twice?

Definitely. A few women we spoke interviewed did have a recurrence of abnormal cells after treatment for CIN3, and this was often found at a follow-up appointment. Most were treated again by LLETZ.

How long does CIN 3 take to develop?

Whereas CIN2/3 typically develops within a few years of infection with HPV (4–6), progression to invasive carcinoma is generally thought to require much more time.

Can CIN3 cause pain?

CIN3 may be referred to as severe dyskaryosis or severe dysplasia. Less commonly, it is called carcinoma-in-situ, though this term is rarely used these days. CIN1, 2 and 3 rarely cause any symptoms, such as pain, discharge or bleeding.

How common is carcinoma in situ cervix?

The mean age at diagnosis is 35–37 years,6,7 and the current incidence rate is approximately 6.6 per 100,000 persons, increasing to 11.2 per 100,000 persons at the peak age of 30–39 years. The average interval between a diagnosis of clinically detectable AIS and early invasive cancer is at least 5 years.

What does CIN 3 mean?

CIN 3. CIN 3 means the full thickness of the cervical surface layer is affected by abnormal cells. CIN 3 is also called carcinoma-in-situ. This sounds like cancer, but CIN 3 is not cervical cancer. Cancer develops when the deeper layers of the cervix are affected by abnormal cells.

Will a hysterectomy cure cin3?

These data suggest that: adequate colposcopy is an accurate method to rule out invasive cervical cancer and abdominal or vaginal hysterectomy is an effective therapeutic procedure in women with CIN III who have completed reproductive function.
