Endocervical brush sampling at the time of Pap smear to detect adenocarcinoma and its precursors is necessary along with doctor/patient vigilance on abdominal symptoms associated with uterine and ovarian carcinoma. The diagnosis of CIN or cervical carcinoma requires a biopsy for histological analysis. [citation needed]
High-grade squamous intraepithelial lesion (HSIL or HGSIL) indicates moderate or severe cervical intraepithelial neoplasia or carcinoma in situ. It is usually diagnosed following a Pap test. In some cases these lesions can lead to invasive cervical cancer, if not followed appropriately. [citation needed] HSIL does not mean that cancer is present.
The term carcinoma in situ may be used interchangeably with high-grade SIL. [8] Ductal carcinoma in situ of the breast is the most common precancer in women. Bowen's disease is a squamous carcinoma in situ of the skin. Colon polyps often contain areas of CIS that will almost always transform into colon cancer if left untreated.
Carcinoma in situ, meaning "cancer in place", represents the transformation of a neoplastic lesion to one in which cells undergo essentially no maturation, thus may be considered cancer-like. In this state, epithelial cells have lost their tissue identity and have reverted to a primitive cell form that grows rapidly and with abnormal regulation ...
The World Health Organization classification system was descriptive of the lesions, naming them mild, moderate, or severe dysplasia or carcinoma in situ (CIS). [ 66 ] [ 67 ] The term cervical intraepithelial neoplasia (CIN) was developed to place emphasis on the spectrum of abnormality in these lesions, and to help standardize treatment. [ 67 ]
A long-awaited study offers hope to women with early stage breast cancer. ... In recent years, many researchers have been focused on DCIS: ductal carcinoma in situ, the earliest stage of cancer ...
Endocervical curettage is a medical procedure used to extract cells of the endocervix to visualize under a microscope. Direct cervical visualization, colposcopy, and even endocervical colposcopy are not enough to fully analyze all areas of the endocervical epithelium and thus endocervical curettage is the method of choice in cases where this is necessary.
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.
