 Another kind of secrecy practiced in medicine is the concealment of surgical wounds and scars. Cosmetic surgeons hide scars inside hairlines and in the creases behind the ears. Breast cancer is no longer the cause for secrecy it once was, yet reconstruction surgery following mastectomy is a kind of concealment. The lure of minimally invasive laparoscopic surgery is not only that it may both reduce the length of hospital stays and the risk of infection, but also that it leaves less prominent and visible scars. Advances in medical imagining, such as the X-ray, MRI, CT scan and ultrasound, allow providers to enter the body and capture information without leaving tell-tale signs of having done so.
