  We propose a series of simulations about the potential use of Boron isotopes
to trigger neutron-free (aneutronic) nuclear reactions in cancer cells through
the interaction with an incoming energetic proton beam, thus resulting in the
emission of characteristic prompt gamma radiation (429 keV, 718 keV and 1435
keV). Furthermore assuming that the Boron isotopes are absorbed in cancer
cells, the three alpha-particles produced in each p-11B aneutronic nuclear
fusion reactions can potentially result in the enhancement of the biological
dose absorbed in the tumor region since these multi-MeV alpha-particles are
stopped inside the single cancer cell, thus allowing to spare the surrounding
tissues. Although a similar approach based on the use of 11B nuclei has been
proposed in [1], our work demonstrate, using Monte Carlo simulations, the
crucial importance of the use of 10B nuclei (in a solution containing also 11B)
for the generation of prompt gamma-rays, which can be applied to medical
imaging. In fact, we demonstrate that the use of 10B nuclei can enhance the
intensity of the 718 keV gamma-ray peak more than 30 times compared to the
solution containing only 11B nuclei. A detailed explanation of the origin of
the different prompt gamma-rays, as well as of their application as real-time
diagnostics during a potential cancer treatment, is here discussed.
