Colposcopy (Ancient Greek: κόλπος, romanized: kolpos, lit. 'hollow, womb, vagina' + skopos 'look at') is a medical diagnostic procedure to visually examine the cervix as well as the vagina and vulva using a colposcope. [1] The main goal of colposcopy is to prevent cervical cancer by detecting and treating precancerous lesions early.
In the developed world, cervical biopsy guided by colposcopy is considered the "gold standard" for diagnosing cervical abnormalities after an abnormal Pap smear. Other techniques such as triple smear are also done after an abnormal Pap smear. [74] The procedure requires a trained colposcopist and can be expensive to perform.
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.

After 10 years, an intention-to-screen analysis showed a significant relative risk reduction of 18% in the risk of colorectal cancer (0.98% in the invited group vs. 1.20% in the usual-care group). The analysis showed no significant change in the risk of death from colorectal cancer (0.28% vs. 0.31%) or in the risk of death from any cause (11.03 ...
I was surprised when the site of my benign breast biopsy (a procedure in which a sample of breast tissue is removed to be tested for cancer), in February, 2023, turned all sorts of colors and ...
A biopsy is a small piece of tissue removed primarily for the purposes of surgical pathology analysis, most often in order to render a definitive diagnosis. Types of biopsies include core biopsies , which are obtained through the use of large-bore needles, sometimes under the guidance of radiological techniques such as ultrasound , CT scan , or ...
A 2005 study found the sensitivity and specificity of cervicography for cervical intraepithelial neoplasia to be 72.3% and 93.2% respectively; [5] however, a 2007 study criticized the sensitivity figure as "likely... inflated" because the "gold standard" of colposcopy/biopsy may have missed cases of cervical intraepithelial neoplasia.
