@resort I had lymphovascular invasion and am 9 years out from diagnosis. It is helpful to know if it is in the lymph or blood vessels, and also if it is "focal" (meaning only around the tumor) or "extensive." I have read that LVI can be seen as equivalent to one positive lymph node but don't know how accurate that is. It is possible that surgery removes LVI. One of my docs said that the significance lies more in the fact that those cells showed an ability to "go somewhere." But many of us with LVI do fine. It sounds scary but docs never even mentioned it to me: I had to ask. (I also wondered if the biopsy could create the appearance of LVI!)
