Cervical Squamous Intraepithelial Neoplasia 1 (CIN 1) is a low-grade lesion of the cervix that is considered a precursor to cervical cancer. It is characterized by mild dysplasia, where there are slight abnormalities in the size, shape, and number of cells on the surface of the cervix.

Causes

CIN 1 is primarily caused by infection with certain types of human papillomavirus (HPV), particularly HPV types 16 and 18, which are known to be high-risk for cervical cancer. Other risk factors include having multiple sexual partners, early onset of sexual activity, and a weakened immune system.

Symptoms

CIN 1 is often asymptomatic, meaning it does not usually cause any noticeable symptoms. It is typically detected through routine Pap smear tests, which are part of regular cervical cancer screening programs.

Diagnosis

The diagnosis of CIN 1 is made through a combination of Pap smear, colposcopy, and biopsy. During a Pap smear, cells from the cervix are collected and examined under a microscope. If abnormalities are detected, a colposcopy may be performed, which involves using a special microscope to closely examine the cervix. A biopsy may be taken to confirm the diagnosis.

Treatment

In many cases, CIN 1 does not require immediate treatment and may resolve on its own. Patients are often monitored with regular follow-up Pap smears and colposcopies. If treatment is necessary, options include cryotherapy, which involves freezing the abnormal cells, or the loop electrosurgical excision procedure (LEEP), which removes the abnormal tissue using a wire loop.

Prognosis

The prognosis for CIN 1 is generally good, especially with regular monitoring. Most cases do not progress to higher-grade lesions or cervical cancer. However, it is important for individuals with CIN 1 to adhere to follow-up care to ensure any changes are detected early.
