I am glad you read it, this subject matter fascinates me.
It’s essentially almost like a new discovery from only 5 years ago. I think we are about to learn much more about the different roles this system (organ) plays.
I am not going to debate about whether some groups have declared it an organ or not. I believe it will be in time anyway.
The research surrounding this is interesting because you have so many people jumping into it that some people are simultaneously saying things like “I think this could be a way cancer moves around the body” and another being like “Yeah, I basically proved that already. I am attempting to figure out how to stop it”
