Since photovoltaic generation greatly affect electricity load behaviour, and is also information currently available to a DNO, we further note the number of generation MPANs on each substation, where each generation MPAN relates to a separate, secondary, MPAN allocated for a property with, say, solar panels.
Once cells spread and survive, they might establish a separate secondary tumor site in a new environment of a host organ (for example, bone marrow, liver, lung or brain).
