Dark matter as a cancer hazard
  We comment on the paper "Dark Matter collisions with the Human Body" by K.
Freese and C. Savage (Phys. Lett. B 717, 25 (2012) [arXiv:1204.1339]) and
describe a dark matter model for which the results of the previous paper do not
quite apply. Within this mirror dark matter model, potentially hazardous
objects, mirror micrometeorites, can exist and may lead to diseases triggered
by multiple mutations, such as cancer, though with very low probability.
