Cervical intraepithelial neoplasia (CIN), also known as cervical dysplasia, is the abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer. [1] More specifically, CIN refers to the potentially precancerous transformation of cells of the cervix.
A precancerous condition is a condition, tumor or lesion involving abnormal cells which are associated with an increased risk of developing into cancer. [ 1 ] [ 2 ] [ 3 ] Clinically, precancerous conditions encompass a variety of abnormal tissues with an increased risk of developing into cancer.
Cervical cancer typically develops from precancerous changes called cervical intraepithelial neoplasia over 10 to 20 years. [3] About 90% of cervical cancer cases are squamous cell carcinomas, 10% are adenocarcinoma, and a small number are other types. [4] Diagnosis is typically by cervical screening followed by a biopsy.

Cevira treatment is administered locally and remains in contact with the cervix to deliver treatment for up to 24 hours. A cup holds the ointment against the cervix for initial absorption. After a few hours, a light source within the cup emits light at a specific wavelength so the Active Pharmaceutical Ingredient , hexylaminolevulinate (HAL ...
The tumors had already spread throughout her abdomen, and doctors removed her uterus, cervix and both ovaries. “The tumors were extensive. They were on both ovaries, all over the uterus,” she ...
The main goal of colposcopy is to prevent cervical cancer by detecting and treating precancerous lesions early. Human Papillomavirus (HPV) is a common infection and the underlying cause for most cervical cancers. Smoking also makes developing cervical abnormalities more likely.
Cervical cancer, considered a “highly preventable” disease, has long been declining in the United States — but it’s now on the rise among women in their 30s and 40s. Rates climbed 1.7 ...
Most HPV infections of the cervix are cleared rapidly by the immune system and do not progress to cervical cancer (see below the Clearance subsection in Virology). Because the process of transforming normal cervical cells into cancerous ones is slow, cancer occurs in people having been infected with HPV for a long time, usually over a decade or ...
