How Is Ferrofluid Utilized in Cancer Treatments?

[Swifters]

Could anyone possibly explain how ferrofluid is used in cancer treatment? Is it via an electromagnet or an alternating current? Have Googled but am none the wiser. Is ferrofluid difficult to warm up? What sort of temperatures are we talking about? Many thanks

Try on Google scholar instead:

A brief scan seems to indicate that they're swirled around to disrupt cancerous cell membranes (thus killing them) or that they're heated up like an induction range (also killing the cells).

Could anyone pass comment on the above? Ferrofluid for central heating?
