Hi So-scared,
Cancer is a real bugger, and does whatever it feels like, as we all (or almost all
) know too well. I always laugh when we talk about "microscopic cells" because they are all, of course, microscopic. The little bastards can start in the lymphatics and migrate from there into the vascular (blood) system, then go anywhere. However, there are some places that they usually "like" to go: areas that closely mimic their host environment (ie colon) ---highly vascular areas (liver and lung), but, because cancer sucks, it can go other places, too, of course. (That is, of course, why Avastin works. It prevents the growth of new vessels at the tumor site to nourish the tumor; that's why it's only given to stage IVs---tumors die, just as everything else does, without a blood supply). I had 3 doses of Avastin, and my large tumor in my liver was 100% dead when it was removed.
To make things even more complicated, it's possible that there may be an
interstitial fluid spread of cancer. Virtually every cell in the body is bathed in interstitial fluid, which ultimately drains into the lymphatic system. it is possible that during surgery, or a biopsy even, a stray cell can get into the interstitial fluid, and begin it's travel to a metastatic site. There is not total agreement on this mechanism. There IS sufficient concern however that in the operating room, there is a table set up, remote from our bodies, that is there specifically for the tumor, any other specimens for pathology, and any instruments that were used in touching our tumors in any way. Our docs are extremely careful in wanting to keep that crap as far away from us, and open incisions, as possible while operating on us. I don't suppose anyone can ever say with 100% certainty, but for my liver tumor, hematogenous spread is the only thing that makes sense to me and my surgeon. I would MUCH prefer it be that way.
I am so glad for you that you only had this very minimal lymphatic involvement. I can't remember, is your liver tumor in the lab yet? (The ONLY place for them to be
)
Best wishes to you!
