Purely a guess on my part, but I imagine a not-insignificant amount of this is simply bloodflow. If cancer is a disruption in the cellular replication mechanics, then we're looking at protein folding, DNA replication, and ion pumps and cell stuff. Perhaps not "taking out the trash" via blood flow allows higher rates of cellular corruption? Maybe lower bloodflow results in weaker cell self-destructs? Lots of candidates...

Since we're guessing, I'd guess lymph is part of it. It's part of our immune systems, but, unlike blood which has its own pumping mechanism (the heart), lymph gets moved along passively.

Does blood "take out the trash too", i didnt realize it serves that dual function. Like I knew it transports oxygen and maybe nutrients vaguely...

It sure does! Blood is carried back to the spleen, kidney, and liver where the blood is "cleaned" of the waste it was carrying before being recirculated. It also carries immune cells to/from your lymph nodes, oxygen, water, all sorts of stuff. Blood is more than just WBC/RBC!

Blood is the lifeblood of the body!

Not joking, has anyone studied the potential anti-cancer benefits of substances that stimulate blood flow like caffeine and niacin?

I'm not sure, but that could be interesting.
