All too often, the most brutal part of a bout with cancer is radiation therapy. X rays are electromagnetic waves that travel with a constant amount of energy, so although they effectively kill cancer cells, they pass through the skin and healthy tissues on their way to and from the tumor. In doing so, they damage the normal cells in their path. Protons, on the other hand, are particles that have a mass and a charge (they are positive). They can thus be targeted with exquisite specificity only to the tumor site, emitting the bulk of their radiation there and there only and sparing patients the terrible side effects that can accompany therapy with X rays.

A New Orleans woman recently lost an arm to necrotizing fasciitis — the so-called “flesh-eating bacteria” — after injecting a drug called “bath salts,” according to a case study report in the medical journal Orthopedics . She presented with cellulitis, a skin infection, two days after attending a party at which she injected the drug. The infection initially responded to administered antibiotics, but then worsened. The woman lost not only her arm, but her breast and a large portion of her chest wall to amputation. The significant removal of tissue was necessary to prevent the spread of the bacteria.
