A complete pelvic exam and yearly Pap test are the best screening tools for vaginal cancer. A test for the human papilloma virus (HPV) may also be given. If an abnormality is found, your physician may perform additional tests, such as:
  • Colposcopy: A special viewing scope with magnifying lenses is used to examine the lining of the vagina.
  • Biopsy: A small sample of abnormal tissue is removed for examination under a microscope for signs of cancerous changes.
In addition to a biopsy, diagnostic equipment may be used to see if the vaginal cancer has spread. This may include:
  • Cystoscopy or proctoscopy: To see if cancer has spread to the urethra or bladder, a thin, lighted tube (cystoscope) is inserted through your urethra. Similarly, a proctoscope is inserted into your rectum to check for cancer there.
  • Computed tomography (CT) scan: combines multiple x-rays to provide three-dimensional clarity and show various types of tissue, including blood vessels. CT not only confirms the presence of a tumor but can show its precise location, size, and involvement with adjacent tissue. 
  • Magnetic resonance imaging (MRI): magnets and radio waves provide three-dimensional images of the body. MRI is used to view biochemical changes in the body to detect cancerous tumors, particularly those that have spread beyond the vagina. It may also be used to determine if a tumor is benign or malignant.
  • Positron emission tomography (PET) scan: A specific dye injected into a vein highlights cancer cells growing anywhere in your body, which can then be detected by a special camera.

Your doctor might first suspect vaginal cancer during a regular pelvic exam or from results from a Pap test. To make an official diagnosis, your doctor might want to further examine your vagina for abnormal cells by performing a colposcopy. In this procedure a small microscope called a colposcope lights up and magnifies the inside of the vagina. A sample of your tissue, called a biopsy, might be taken from your vagina to send to a laboratory to test for the presence of cancer cells.

Vaginal Cancer

Although less common than other types of gynecologic cancers, vaginal cancer can be very deadly once it spreads to other parts of the body.Several types of vaginal cancer exist, with the most common being squamous cell carcinoma, ...

which typically develops in the upper region of the vagina. Less than 3% of gynecologic cancers begin in the vagina, although several other cancer types commonly spread to this area. It is unknown what causes vaginal cancer, but several factors increase your risk to develop the disease. If youre over the age of 60, have the human papillomavirus (HPV) or have had other gynecologic cancers like cervical cancer, youre more likely to develop this disease. See your doctor if you have a bloody and rank smelling vaginal discharge, notice painful urination or pelvic pain, or feel a lump in your vagina.
