Is CIN 1 the same as dysplasia?
CIN 1 is not cancer and usually goes away on its own without treatment, but sometimes it can become cancer and spread into nearby tissue. CIN 1 is sometimes called low-grade or mild dysplasia. Also called cervical squamous intraepithelial neoplasia 1.
Does CIN 1 Go Away?
Nearly all of the low-grade abnormalities (CIN-1) will go away without treatment, as they are due to an HPV infection. Treatment is no longer recommended for this abnormality as the harm outweighs the benefits. In a small number of women, the low-grade abnormality persists, or rarely, progresses to a high-grade change.
What causes mild dysplasia CIN?
A common virus called human papillomavirus (HPV) can cause cervical dysplasia. It is the most common sexually transmitted virus in the United States. Other independent risk factors, such as radiation exposure, smoking, and vaginal inflammation, may also contribute to the development of cervical dysplasia.
What is mild cervical dysplasia CIN1?
CIN 1 (mild dysplasia): Considered a low-grade lesion, CIN 1 refers to dysplasia confined to one-third of the thickness of the cervical lining. CIN 2 (moderate dysplasia): Considered a high-grade lesion, CIN 2 signifies approximately two-thirds of the cervical cells are abnormal.
Should I worry about mild dysplasia?
Often, with mild dysplasia (CIN I), no treatment is needed. In most cases, mild dysplasia resolves on its own and doesn’t become cancerous. Your doctor may recommend follow-up in a year to check for additional changes.
How long does it take for CIN1 to become CIN 2?
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.
Is CIN1 normal?
The majority of low grade changes i.e. CIN1, are harmless and return to normal by themselves. People with high grade changes, i.e. CIN2 or 3, are treated to avoid the risk of progressing to cancer. High grade changes are not cancers and they take many many years to turn into cancer.
Is CIN1 an ascus?
CIN1, cervical intraepithelial neoplasia grade 1; HPV, human papillomavirus; ASCUS, atypical squamous cells of undetermined significance; LSIL, low-grade squamous intraepithelial lesions.
