An imaging device may during a pelvic examination, illuminate a tissue with a blue light, the tissue including at least one of a cervix uteri or vaginal wall. The blue light has a wavelength of between 390 nm and 480 nm and is selected to induce fluorescence in at least one biomarker in cells of the tissue, resulting in fluoresced tissue. An imaging device may capture an image of the tissue including the fluoresced tissue. An imaging device may identify, in the image, an indication of cancer based on the fluoresced tissue.

A device, comprising: a tubular member which is flexible, the tubular member forming a channel when in an open and active configuration and the tubular member narrowed when in a closed and inactive configuration. The device, once expanded into the open and active configuration provides for a channel. The channel provides for a passthrough for medical instruments.
