Yes but cleavage of the ring doesn't give ortho aminophenol, ir gives 4-amino-3-hydroxyamphetamine and the reason most carcinogens like that are so dodgy is that the body resorts to desparate metabolic measures to make the substance polar to facilitate excretion. The 2-aminopropyl contains a polar non aromatic amine group that can give the body (well kidneys) the handle with which to remove it from the bloodtream. it's analogous to the relationship between benzrne and amphetamine, yet amphetamine doesn't cause bladder cancer as it's not formed into the epoxide metabolite the way benzene is. similarly, aromatic amines are well didgy, but para-aminobenzoic acid it totally safe because of the polarity of the carboxylate group
