    I’ve been pondering how it is evident that there is no lymphatic or blood vessel invasion

    Is this because they see the vessels in the sample and note that there is no sign of mel movement through them?

    It’s the only thing that’s still got me worried about my biopsy results and a little clarification would go along way in calming my nerves!

    As with any cancer, the only way you know you have it is when it forms a tumor that is seen on a CT scan. In the meantime, most of the cancer cells are microscopic and you can’t see them. But your immune system can spot them and eliminate them So try not to worry as it lowers your immune system.


    You’re asking how does the pathologist determine no lymphovascular or angioinvasion? I don’t know, there must be something they look at under the microscope when they are doing the pathology that allows them to determine if lymphovascular invasion or angioinvasion is present or absent.
