In the event that, or with the risk of the cancer (spreading to) in the lymph nodes / lymph system, with the massage being performed to get the lymph moving and out of the body and through other organs.

Yes I do not know anything about this or much about the body which is why I ask and it probably sounds completely stupid and wrong. But it seems too complex to look up myself so does anyone know the answer and can they explain (even in a nutshell)

I mean someone who had cancer but it wasn't in their lymph nodes/system but of course unless they are being tested for it everyday it could at any time spread. So in that case if anyone wants to write, I would be interested to know what would actually happen if it was done knowingly on someone who had cancer in the lymph
lymphatic massage/drainage. Manual massage for drainage purposes
