If you have abnormal Pap or HPV test results, your doctor will suggest other tests to make a diagnosis:
*'''[[Biopsy]]''': Most women have tissue removed in the doctor's office with local anesthesia. A [[pathologist]] checks the tissue under a microscope for abnormal cells.
*'''[[Colposcopy]]''': The doctor uses a colposcope to look at the cervix. The colposcope combines a bright light with a magnifying lens to make tissue easier to see. It is not inserted into the vagina. A colposcopy is usually done in the doctor's office or clinic.
**'''[[Punch biopsy]]:''' The doctor uses a sharp tool to pinch off small samples of [[cervical]] tissue.  
 
**'''[[Loop electrosurgical excision procedure]](LEEP):''' The doctor uses an electric wire loop to slice off a thin, round piece of [[cervical]] tissue, this method allows deep excision of the [[transformation zone]].  
*'''[[Biopsy]]''': Most women have tissue removed in the doctor's office with local anesthesia. A pathologist checks the tissue under a microscope for abnormal cells.
**'''Endocervical [[curettage]]:''' The doctor uses a curette (a small, spoon-shaped instrument) to scrape a small sample of tissue from the cervix. Some doctors may use a thin, soft brush instead of a curette.  
**'''Punch biopsy:''' The doctor uses a sharp tool to pinch off small samples of cervical tissue.  
**'''[[Conization]]:''' A conization, or cold knife [[cone biopsy]], cone shaped samples are removed from [[cervix]] and allows for accurate examination of biopsy speciemen by [[pathologists]].This can be done in doctor's office or in the hospital under general anesthesia.

**'''Endocervical curettage:''' The doctor uses a curette (a small, spoon-shaped instrument) to scrape a small sample of tissue from the cervix. Some doctors may use a thin, soft brush instead of a curette.  
**'''Conization:''' The doctor removes a cone-shaped sample of tissue. A conization, or cone biopsy, lets the pathologist see if abnormal cells are in the tissue beneath the surface of the cervix. The doctor may do this test in the hospital under general anesthesia.
 
Removing tissue from the cervix may cause some bleeding or other discharge. The area usually heals quickly. Some women also feel some pain similar to menstrual cramps. Your doctor can suggest medicine that will help relieve your pain.

Overview

There are other important diagnostic tools for diagnosing cervical neoplasia, these are include colposcopy and biopsy, cold knife conization, endocervical curettage. Cervical biopsy is the confirmatory test for the diagnosis of cervical cancer or pre-cancer, this can be done in doctor's office via colposcopy.

Other Diagnostic Studies

Biopsy

  • This is often done through colposcopy, a magnified visual inspection of the cervix aided by using an acetic acid solution to highlight abnormal cells on the surface of the cervix.
  • Biopsy: Most women have tissue removed in the doctor's office with local anesthesia. A pathologist checks the tissue under a microscope for abnormal cells.
    • Punch biopsy: The doctor uses a sharp tool to pinch off small samples of cervical tissue.
    • Loop electrosurgical excision procedure(LEEP): The doctor uses an electric wire loop to slice off a thin, round piece of cervical tissue, this method allows deep excision of the transformation zone.
    • Endocervical curettage: The doctor uses a curette (a small, spoon-shaped instrument) to scrape a small sample of tissue from the cervix. Some doctors may use a thin, soft brush instead of a curette.
    • Conization: A conization, or cold knife cone biopsy, cone shaped samples are removed from cervix and allows for accurate examination of biopsy speciemen by pathologists.This can be done in doctor's office or in the hospital under general anesthesia. Most significant complication of this method is hemorrhage. There is relative contraindication for pregnant women and also conization increase the risk of preterm birth. [2][3]
