Which of the following is a diagnostic procedure for cervical cancer?

Colonoscopy
Colposcopy
MRI scan
CT scan

The correct answer is: Colposcopy

Colposcopy is a diagnostic procedure specifically designed to examine the cervix, vagina, and vulva for signs of disease, making it essential in the evaluation of cervical cancer. During colposcopy, a special instrument called a colposcope is used to magnify the view of the cervix, allowing healthcare providers to identify any abnormal areas that may require further investigation or biopsy. This procedure is often performed after an abnormal Pap smear or positive HPV test, as it allows for targeted biopsies of suspicious areas. The identified lesions can then be analyzed for the presence of precancerous changes or cervical cancer itself. Other procedures, such as colonoscopy, are aimed at the colon and rectum and are not relevant for diagnosing cervical issues. Similarly, while MRI and CT scans can provide valuable information in staging cervical cancer or assessing the extent of the disease, they do not serve as primary diagnostic tools for detecting cervical cancer itself. Therefore, colposcopy stands out as the most appropriate and specific diagnostic procedure for this type of cancer.
