An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...
Cervical conization refers to an excision of a cone-shaped portion of tissue from the mucous membrane of the cervix. Conization is used for diagnostic purposes as part of a biopsy and for therapeutic purposes to remove pre-cancerous cells ( cervical intraepithelial neoplasia ) or early stage cervical 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. [2]
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.
Cervical squamous intraepithelial lesion (SIL), previously called cervical intraepithelial neoplasia (CIN), is a form of dysplasia that can progress to cervical cancer. 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.
Cervical cancer is treated with surgery up to stage 2A. [ 31 ] [ 38 ] Local excision via loop cone biopsy is sufficient if detected in the earliest stage. [ 31 ] [ 38 ] If a patient presents beyond this point, bilateral lymphadenectomy is performed to assess metastasis to pelvic lymph nodes. [ 31 ]
A cervical polyp is a common benign polyp or tumour on the surface of the cervical canal. [2] They can cause irregular menstrual bleeding but often show no symptoms. Treatment consists of simple removal of the polyp and prognosis is generally good. About 1% of cervical polyps will show neoplastic change which may lead to cancer.
The polyps are routinely removed at the time of colonoscopy, either with a wire loop known as a polypectomy snare (first description by P. Deyhle, Germany, 1970), [12] or with biopsy forceps. If an adenomatous polyp is found, it must be removed, since such a polyp is pre-cancerous and has a propensity to become cancerous.
