Tumo(u)rs attract a blood supply when they become malignant.
A substance named Tumo(u)r Angiogenesis Factor has been named
as the agent which attracts arteries - it has never been
identified. (As far as I know...).

Other entities (I wish you hadn't called them that) would include:
fun, love, guilt, vital spirit, truth, certainty, accident, ...

Of course, some of these "entities" are marvelous for developing
an appreciation of something else (which also may not "exist"
-go back to school...).
