Antiprotons excel at cancer treatment

A beam of antiprotons should be four times better at destroying tumours
than current proton-beam therapies, claim physicists at CERN. The
discovery could lead to new cancer-treatment techniques that minimize
the damage done to healthy tissue surrounding tumours (Radiother.
Oncol. 2006 doi:10.1016/j.radonc.2006.09.012).
Proton-beam therapy is a very effective way of destroying tumour cells
in the body because protons deposit most of their energy at a precise
depth in human tissue. This depth is a function of proton energy, which
can be set to minimize the energy absorbed by healthy tissue
surrounding a tumour.
