I've been trying to avoid going "all out medical" on any of my answers, as I think that's more in line with the theme on the site. However, on this question, I didn't really think there was a good way to answer the question without graphic and possibly disturbing images.
While not disturbing to me, I know people (like my wife) who are greatly disturbed by such images. This may be the only SE where it is likely to content that could be both appropriate and also offensive. What sort of warnings should we put up. I noticed on my larger monitor in my office that by the time my warning loaded, the surgical images could be seen. Therefore it might have been useless.
Also, as someone from possibly the other side of the wave, I feel all of medicine can really fall under the umbrella of biology (but clearly asking for medical advice isn't). I feel like we still feel shaky on medical topics. That's probably because there are few here with medical expertise, and as I mentioned in chat, most professionals I float this by would consider it an additional step (lit reviews being our bread and butter).
