According to David Nellis in "Poisonous Plants and Animals of Florida and the Caribbean", Euphorbia tirucalli can infuse the soil around it with poisons in order to repel other plants.  It is possible that these poisons are carcinogenic.  I have removed several of my specimens and put the others into planters.  The sap is very irritating to skin and eyes.
