I have to have yearly up to this year, then two yearly cystoscopy. This after kidney cancer. I have no problem with the procedure just the embarrassment of multiple small sebaceous on the edge of my labia major. They started about 25 years ago with two or three. Once I past 50 they increased. My sister also has several but not as many as me. I'm sure the medical staff are used to these things but I am so embarrassed and ashamed.
These little cysts are really quite common. They form when the entrance to the sebaceous glands become blocked, and as there are numerous of these lubricating glands in the genital area, they often develop there. They can vary in size from just a little yellow pin head, to something larger, like a small grape. There really is no need to be embarrassed or ashamed – I suspect the medical staff won’t even notice them when they are doing the cystoscopy as they are so common. However, if they are bothering you, you can ask your GP whether she could help with their removal. This usually involves piercing the overlying skin with a sterile needle, then squeezing out the contents. It can be a bit uncomfortable, and the skin around can be a bit sore afterwards, so I generally only deal with a few at a time. It’s also, strictly speaking, a cosmetic procedure, and so not available on the NHS, but a sympathetic GP will hopefully understand your predicament and not refuse your request.
