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).
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.
Does cin1 need treatment?
CIN 1 – it’s unlikely the cells will become cancerous and they may go away on their own; no treatment is needed and you’ll be invited for a cervical screening test in 12 months to check they’ve gone. CIN 2 – there’s a moderate chance the cells will become cancerous and treatment to remove them is usually recommended.
Can a cervical biopsy remove abnormal cells?
Cervical biopsies can be done in several ways. The biopsy can remove a sample of tissue for testing. It can also be used to completely take out abnormal tissue. It can also treat cells that may turn into cancer.
Does CIN 2 come back?
Women treated for CIN2 or CIN3 retain an elevated risk of recurrence or even invasive cancer for years following treatment (2, 3). Thus, heightened surveillance has been the rule, with uncertainty as to whether (and when) a return to normal screening intervals can be safely permitted.
How quickly does CIN 2 progress?
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.
How serious is CIN 2?
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 CIN 2 come back?
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 are the chances of CIN 2 returning?
Five-year risks of recurrent CIN2+ after treatment varied both by antecedent screening test result and the histology of the treated lesion. The risk ranged from 5% for CIN2 preceded by HPV-positive/ASC-US or LSIL to 16% for CIN3/AIS preceded by AGC/ASC-H/HSIL+ (p<0.0001).
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.
