Proctosigmoidoscopy and cystoscopy for vulvar cancer

Proctosigmoidoscopy and cystoscopy are used to detect if the cancer has spread to the rectum, colon or bladder.

What is a proctosigmoidoscopy and cystoscopy?

In these two similar procedures, a doctor will use a flexible, thin hollow tube with a lens and a light on the end to examine the rectum and colon or the bladder. A proctosigmoidoscopy is used to examine the rectum and colon, while a cystoscopy is used to view the bladder.
