How does phytoplankton help fight cancer?

ive heard two different stories: one is by Word of mouth. supposedly the skeleton of plankton are so small and pointy (sharp) that when these skeletons passes through the body, via bloodstream, they chop up any unnaturaldiseases. they do not hurt the actual body because we are too big for the sharp skeletons to actually cause us harm.

the second, through reading on throughout the wed. supposedly plankton are a superfood; meaning they are entirely made up of vitamins, nutrients, and other holesome things our body needs. so there is no toxic to fuel cancer from growing. in addition they super heal the body, giving it a super dose of goodness to fight off the disease(s).
