Vulvar Cancer: The Basics
The vulva is the outside part of woman’s sex organs. The vulva is made up of the labia, clitoris, mons pubis, the entryway to the vagina (vestibule), and the perineum. Vulvar cancer is cancer that starts in the vulva. It is caused by vulvar cells growing out of control. As the number of cells grows, they form into a tumor.
Vulvar cancer that has spread from the vulva to another part of the body is called metastatic cancer.
Some risks include:
- Having gone through menopause.
- Infection with HPV.
- Having had some other gynecologic cancer or melanoma in the past.
Signs of Vulvar Cancer
The signs can include:
- Pain with sex.
- Bleeding and/or discharge.
- Lesions or new skin growths.
Diagnosis of Vulvar Cancer
When your healthcare providers think you may have vulvar cancer, they will order tests. Here are some of the tests:
- Colposcopy and vulvoscopy.
- Pap test.
These tests are important but a biopsy is the only way to know for sure if you have cancer. A biopsy:
- Looks at a piece of the vulva for cancer cells.
- Is used to find out the cancer type, how normal it is [grade], and if it has spread.
- May look at samples from lymph nodes to check for cancer.
A pathology report sums up these results and is sent to your healthcare provider, often 5-10 days after the colposcopy or vulvoscopy. This report is an important part of planning your treatment. You can ask for a copy of your report for your records.
Staging Vulvar Cancer
To guide treatment, vulvar cancer is "staged." This stage is based on:
- Size and location of the tumor.
- Whether cancer cells are in the lymph nodes.
- Whether cancer cells are in other parts of the body.
Stages range from stage I (smallest, most confined tumors) to stage IV (tumors that have spread to other parts of the body, also called metastatic cancer). The stage and type of vulvar cancer will guide your treatment plan.
Often, these treatments are used:
- Surgery can be used to remove the cancer.
- Radiation, the use of high energy x-rays to kill cancer cells, can be used.
- Chemotherapy, the use of medications to kill cancer cells, can be given.
